Typhoon natural disasters belong to one of the four major categories of public safety events. Typhoons have stochastic uncertainty and dynamic complexity, and frequent typhoons often cause heavy casualties and property losses in China's coastal areas, seriously affecting economic development and social stability. With the rapid development of artificial intelligence (AI) technology, intelligent disaster prevention and mitigation will become the trend of future development and a hot spot for research.

Owing to the distinctive characteristics of high power density and high efficiency, permanent magnet synchronous motor (PMSM) has drawn extensive popularity over the last several decades [1,2,3]. For this reason, PMSM has been widely applied for industry, especially for electric vehicles, vacuum cleaners, electric ship propulsion and more. Nevertheless, the traditional proportional integral (PI) control algorithm is typically difficult to offer the high-precision control property [4,5,6,7]. To improve the unsatisfactory performance of the PI controller, lots of advanced algorithms have been applied to further optimize the control precision, such as predictive control [8,9], fuzzy control [10,11,12,13], adaptive control [14,15,16,17,18] and sliding mode control (SMC) [19,20,21,22,23].
Among the previously mentioned modern control approaches, the SMC is an effective strategy to enhance the anti-disturbance capability of the PMSM system [24]. A traditional linear SMC method was presented in [25] to obtain a fast dynamic response and strong robustness. However, the parameter variation has not been completely considered in theory, which limits the stable operation of motors. In [26], a new piecewise but differentiable switching controller was introduced with a proper design idea to avert the singularity problem. Moreover, in order to make the speed error converge faster, the nonsingular terminal sliding mode (NTSM) control algorithm was proposed [27] to make sure that the speed error will finite-time converge to the origin.
The NTSM strategy can handle the singular issue and provide satisfactory tracking accuracy. However, the NTSM controller still brings severe chattering[28,29], and a fast NTSM controller with no switching function was used to weaken the chattering [30]. However, this kind of controller has poor anti-disturbance performance and only converges the speed error to a region instead of to zero. At the same time, a brand-new adaptive terminal sliding mode (TSM) reaching law combined with a fast TSM control method was utilized to construct the speed controller for the PMSM system in [31]. Even if an adaptive law was adopted to reduce chattering, this method still cannot adjust the control gain automatically with the change of total disturbance.
Notably, utilizing the disturbance observer (DOB) to estimate the unknown time-varying disturbance is a valid strategy to avoid the overestimated switching gain in SMC [32,33,34]. Compensating the precise estimates to the baseline controller, the PMSM drive system will achieve significant steady-state performance and strong disturbance rejection property synchronously [35]. Without the accurate information of the PMSM mathematical model, a conventional extended state observer (ESO) was applied [36] to restrain the property deterioration of PMSM in the existence of external disturbance and parameter variation. Unfortunately, the baseline controller only adopted the linear PI method. It is extremely hard for this category of composite controllers to achieve strong disturbance rejection property. On this basis, the traditional ESO combined with a simple SMC algorithm was constructed [37] to address the above tough issue. Although the traditional ESO can estimate the total disturbance exactly, it just guarantees that the estimated error converges asymptotically to zero, which may result in poor estimation precision. In order to obtain higher estimation accuracy and robustness, various improved ESOs have been proposed in recent years[38,39]. In [40], the natural evolution theory has been applied to graph structure learning, where an evolutionary method was constructed to evolve a population of graph neural network (GNN) models to adapt to dynamical environments. In [41], a heterogeneous network representation learning method was reported to characterize implicitly inside Ethereum transactions. In [42], a center-based transfer feature learning with classifier adaptation for the surface defect recognition was proposed. In [43], the authors proposed an integrated triboelectric nanogenerator and tribovoltaic nanogenerator in the air cylinder as difunctional pneumatic sensors for simultaneous position and velocity monitoring. In [44], the recent developments in the area of arc fault detection were studied.
In this paper, a novel adaptive nonsingular terminal sliding mode (ANTSM) controller combined with a modified ESO (MESO) is proposed to enhance the disturbance rejection property of the PMSM system. First of all, considering the parameter variation and time-varying load torque, an ANTSM controller is constructed to provide the desired steady-state and dynamic performance. Furthermore, in order to solve the trouble of unsatisfactory control effect due to large switching gain, one novel MESO is utilized to observe the unknown time-varying disturbance and compensate the estimates to the ANTSM controller simultaneously. Lastly, the validity of the ANTSM + ESO composite control algorithm is proved by comprehensive experiments. The main contribution of this article could be summarized in the following points:
1) A novel NTSM controller is designed. The control gain is automatically tuned by the proposed adaptive law. It avoids unsatisfactory control performance caused by excessive control gain.
2) A MESO is proposed to improve the anti-disturbance capability of the PMSM system. By using the finite-time technique, the estimation error can converge to zero in finite time. The proposed MESO has a higher estimation accuracy and faster estimation speed.
3) The proposed composite controller combines the ANTSM algorithm with MESO to improve the system robustness. Since the high disturbance estimation accuracy of MESO, the rejection ability to disturbances of the PMSM speed regulation system can be improved.
The rest of the paper is organized as follows. In Section 2, the PMSM mathematical model with parameter perturbation and the traditional NTSM control method are described. Section 3 shows the design of the proposed MESO-based ANTSM controller in detail. Comprehensive experiments are illustrated in Section 4. The summary of this paper is presented in Section 5.
Notations: Throughout the paper, the symbol ⌊x⌉m is used to present the |x|m⋅sign(x) for a real number m, and the symbol ⌊x⌉∗ is defined as
⌊x⌉∗={1,x≥00,x<0. |
In the ideal case, the motion equation of PMSM can be given by
˙Ω=1.5npψfJiq−BJΩ−TLJ | (2.1) |
where Ω is the rotor angular speed, np is the number of pole pairs, ψf is the flux linkage, J is the moment of inertia, B is the viscous friction coefficient, iq is the stator current in the q-axis and TL is the load torque.
Because of load variation in practical applications, the value of inertia may be mismatched. Therefore, we introduce ΔJ=J−J0, where J0 is the nominal value and ΔJ is parameter variation. Then, replacing current iq by the reference current i∗q, system (1) can be rewritten as
˙Ω=1.5npψfJ0iq−BJ0Ω+d0(t)=bi∗q−BJ0Ω+d0(t) | (2.2) |
where d0(t)=−TLJ0+b(iq−i∗q)−ΔJJ0˙Ω and b=1.5npψfJ0.
The traditional NTSM algorithm is used to design the speed controller for the PMSM system in this subsection. First of all, setting Ωr as the reference speed, the speed error Ωe is expressed as
Ωe=Ωr−Ω. | (2.3) |
With the help of (2.2), one has
˙Ωe=−bi∗q−BJ0Ωe+d(t) | (2.4) |
where d(t)=−d0(t)+˙Ωr+BJ0Ωr is the total disturbance.
Assumption 1: [45,46,47] The total disturbance d(t) is bounded and differentiable, and there exist known positive constants l1 and l2 such that |d(t)|≤l1 and |˙d(t)|≤l2.
Remark 1: From (2.2) and (2.4), we can get that the disturbance d(t) consists of the load torque TL, the stator current iq, the stator reference current i∗q, the speed Ω, the setting speed Ωr and other components. It can be concluded that the above variables are bounded and differentiable. Therefore, it is reasonable that the total disturbance satisfies |d(t)|≤l1 and |˙d(t)|≤l2, where l1 and l2 are known positive constants.
According to [48], the nonsingular terminal sliding manifold is selected as
s=∫Ωedt+1βΩp/qe | (2.5) |
where β is positive constant, p and q are positive odd integers and 1<p/q<2.
Based on this, the NTSM controller will be designed as
i∗q=1b(−BJ0Ωe+βqpΩ2−p/qe+k⋅sign(s)) | (2.6) |
with a positive constant k.
Choose the widely-used Lyapunov function as
V(s)=12s2. | (2.7) |
Differentiating V(s) gets
˙V(s)=s˙s=s(Ωe+pβqΩp/q−1e˙Ωe)=spβqΩp/q−1e(−bi∗q−BJ0Ωe+d(t)+βqpΩ2−p/qe). | (2.8) |
Substituting NTSM controller (2.6) into (2.8), one obtains
˙V(s)=spβqΩp/q−1e(−k⋅sign(s)+d(t))≤−pβqΩp/q−1e|s|k+pβqxp/q−1|s||d(t)|≤−pβqΩp/q−1e|s|(k−l1). | (2.9) |
Similar to [27], if the control gain satisfies k>l1, then the speed error will converge to origin in a finite time.
Remark 2: To guarantee the stability of the PMSM, the value of k in the traditional NTSM controller should be chosen to be larger than the upper bound of the total disturbance. However, the total disturbance in practical engineering is time-varying, and its upper bound may be much smaller than the fixed control gain. Since the control gain directly affects the chattering amplitude, conservative control gain may lead to unsatisfactory control performance in PMSM. Thus, it is urgent to design a novel controller with variable and a small enough control gain to suppress the time-varying disturbance.
To address the forgoing disadvantages of the conventional NTSM controller, a novel ANTSM is developed in this section to automatically tune the value of control gains. Based upon this, compensating the disturbance estimation value derived by MESO to the ANTSM controller, the control gain can get a further reduction.
With the aid of controller (2.6), the ANTSM controller is constructed as
i∗q=1b(−BJ0Ωe+βqpΩ2−p/qe+k(t)⋅sign(s)). | (3.1) |
The adaptive law k(t) is given as
{˙k(t)=η⋅k(t)⋅sign(δ(t))+N[kM−k(t)]∗+N[km−k(t)]∗δ(t)=|[sign(s)]av|−ε, | (3.2) |
where kM>l1 and km>0 are the maximums and minimums of the control gain, constant ε∈(0,1), η>l2εkm, N>ηkM, and [sign(s)]av is produced by the signal z(t) of the low-pass filter
˙z=1λ(sign(s)−z),z(0)=0 | (3.3) |
with λ being the tunable parameter. The ANTSM controller structure is depicted by Figure 1.
Remark 3: Since the discontinuous switching function sign(s) varies at negative one and one, the function [sign(s)]av is continuous and its value belongs to (−1,1). Therefore, it can be assumed that the second derivative of function [sign(s)]av satisfies |d2dt2[sign(s)]av|≤C and C>0.
Next, we will prove that k(t) can converge in a finite time to the minimum absolute value of the total uncertainty. In addition, the equivalent control theory is crucial for the proof in the paper.
The equivalent controller is constructed as
ueq=1b(−BJ0Ωe+βqpΩ2−p/qe+d(t)). | (3.4) |
Since the exact information about the total disturbance d(t) is not available, the equivalent controller (3.4) cannot be directly applied to the PMSM system. Therefore, an average control of ANTSM controller (3.1) is employed to track controller (3.4). Meanwhile, to enhance the accuracy of the average control, a continuous function [sign(s)]av is used to replace the discontinuous function sign(s) in equivalent controller. Then, the average control of ANTSM controller (3.1) is constructed as
uav=1b(−BJ0Ωe+βqpΩ2−p/qe+k(t)⋅[sign(s)]av). | (3.5) |
According to the above analysis, if the average control (3.5) can track the equivalent controller (3.4) well, one has
d(t)=k(t)⋅[sign(s)]av. | (3.6) |
If [sign(s)]av approaches one, the k(t) is sufficiently large to counteract the d(t). The basic idea of the ANTSM control approach is to ensure that k(t) can converge to |d(t)||[sign(s)]av| with ε being close to one in a finite time. Meanwhile, the continuous function [sign(s)]av should converge to parameter ε.
Consider the following Lyapunov function:
V1(δ)=12δ2. | (3.7) |
Evaluating the derivative of V1(δ) yields
˙V1(δ)=δ˙δ=δddt(|d(t)|k(t)). | (3.8) |
Since the range of control gain k(t)∈[km,kM], one has |d(t)|ε>km. With the help of Assumption 1, (3.8) can be rewritten as
˙V1(δ)≤−|δ|k−1(t)(εkmη−l2). | (3.9) |
Combining η>l2εkm and (3.9), one has
˙V1(δ)≤−|δ|(εkmη−l2)kM=−κV121(δ) | (3.10) |
where κ=√2(εkmη−l2)kM>0.
Therefore, inequity (3.10) satisfies the finite-time stability theorem [49], and it indicates that k(t) will converge to |d(t)|ε.
In this subsection, the conventional ESO and the presented MESO are exploited to estimate the disturbance d0(t), respectively. First, provided that |˙d0|≤l0,l0>0, the traditional ESO designed for system (2.2) can be expressed as
{˙ˆΩ=ˆd0−BJ0Ω+bi∗q−h1˜Ω,˙ˆd0=−h2˜Ω | (3.11) |
where ˜Ω=ˆΩ−Ω, ˆΩ and ˆd0 are the estimated values of Ω and d0, h1 and h2 are the gains of traditional ESO.
Nevertheless, the traditional ESO just ensures that the estimation of error converges to zero asymptotically, which causes poor estimation precision. Therefore, it is urgent to accelerate the estimation speed of traditional ESO. For (2.2), the MESO is constructed as
{˙ˆΩ=ˆd0−BJ0Ω+bi∗q−h1ϕ1(˜Ω),˙ˆd0=−h2ϕ2(˜Ω) | (3.12) |
where functions ϕ1(˜Ω) and ϕ2(˜Ω) are given by
ϕ1(˜Ω)=⌊˜Ω⌉12+˜Ω,ϕ2(˜Ω)=12sign(˜Ω)+32⌊˜Ω⌉12+˜Ω. | (3.13) |
Subtracting (3.12) from (2.2) obtains
{˙˜Ω=˜d0−h1ϕ1(˜Ω),˙˜d0=−h2ϕ2(˜Ω)−˙d0 | (3.14) |
where ˜d0=ˆd0−d0.
By defining ξT=[ϕ1(˜Ω),˜d0], the time derivative of ξ can be written as
˙ξ=Φ(˜Ω)[−h1ϕ1(˜Ω)+˜d0−h2ϕ1(˜Ω)−˙d0Φ(˜Ω)]=Φ(˜Ω)(Aξ−Bψ) | (3.15) |
where A=[−h11−h20], B=[01], Φ(˜Ω)=32|˜Ω|12+1 and ψ=˙d0/Φ(˜Ω).
With the help of |˙d0|≤l0, one yields |ψ|≤l0. Then, we define
Γ(ψ,ξ)=[ξψ]T[l2000−1][ξψ]=[ϕ1(˜Ω)˜d0ψ][l2000−1][ϕ1(˜Ω)˜d0ψ]=[ξTψ][l2000−1][ξψ]=−ψ2+l20≥0. | (3.16) |
Theorem 1: For a positive constant γ and the symmetric and positive definite matrix Q, if the following inequality holds
[ATQ+QA+γQ+l20QBBTQ−1]≤0, |
then the estimation error of the proposed MESO (3.12) will converge to zero in a finite time.
Proof. The Lyapunov function is chosen as
V2=ξTQξ. | (3.17) |
From (3.15) and (3.16), the differential coefficient of V2 can be given as
˙V2=Φ(˜Ω)[ξT(ATQ+PA)ξ+ψBTQξ+ξTQBψ]=Φ(˜Ω)[ξψ]T[ATQ+QAQBBTQ0][ξψ]≤Φ(˜Ω){[ξψ]T[ATQ+QAQBBTQ0][ξψ]+Γ(ψ,ξ)}≤Φ(˜Ω)[ξψ]T[−γQ000][ξψ]=Φ(˜Ω)(−γξTQξ)=−Φ(˜Ω)γV2=−12|˜Ω|12γV2−γV2. | (3.18) |
From (3.17), it is derived that
λmin{Q}‖ξ‖22≤ξTQξ≤λmax{Q}‖ξ‖22 | (3.19) |
where λ{⋅} is the eigenvalue of matrix {⋅} and ‖ξ‖22 is the Euclidean norm of ξ.
Considering ‖ξ‖22=|˜Ω|+2|˜Ω|32+˜Ω2+˜d20, it follows that
|˜Ω|12≤‖ξ‖2≤V122λ12min{P}. | (3.20) |
In accordance with (3.18) and (3.20), one obtains
˙V2≤−12|˜Ω|12γV2−γV2≤−γλ12min{P}2V122−γV2. | (3.21) |
Clearly, (3.21) satisfies the finite-time stability theory [50]. To this end, we have proved that under the proposed MESO (3.12) the estimation error will be guaranteed to converge to zero in a finite time.
The proposed MESO can estimate the disturbance precisely. Then, compensating the estimate ˆd0(t) to the baseline controller, the output signal of the MESO-based ANTSM controller can be designed as
i∗q=1b(−BJ0Ωe+βqpx2−p/q+k(t)⋅sign(s)−ˆd0(t)). | (3.22) |
Aiming to validate the performance of the ANTSM + MESO control algorithm, comprehensive experimental results are given in this section. The complete schematic of the proposed ANTSM + MESO control system is illustrated in Figure 4. The experimental platform mainly consists of a three-phase motor, a controller, a three-phase inverter, a host computer and more. The controlled motor is a permanent magnet synchronous motor with a power of 1.5 KW, and the motor parameters are illustrated in Table 1. The controller is based on the RTU-BOX204 real-time digital control platform. The magnetic powder brake is used to generate the load torque. The parameters of the ANTSM controller are chosen as β=600, q=11, p=17, η=1.5, ε=0.99, N=80, km=1 and kM=30, and the parameters of MESO are selected as h1=30 and h2=225.

The start-up results of ω, iq and ia under the PI, traditional NTSM and the proposed ANTSM controller are respectively depicted in Figure 5. The given speed is 500 rpm, and no additional load torque was added. One can notice that the start-up transient response under the PI has the longest convergence time and largest speed overshoot. In Figure 5(c), the developed ANTSM controller has the smaller start speed overshoot. Figure 6 shows a sudden load experiment. From the experimental results, one can see that the proposed ANTSM controller has the smallest speed fluctuation and current ripple.
In this subsection, the ESO-based ANTSM controller is utilized to compare with the presented MESO-based ANTSM controller. Figure 7 exhibits the sudden load change responses at the speed of 500 rpm. After loading, the speed recovery time under the proposed ANTSM+MESO controller is shorter than that under the ANTSM+ESO controller, and the speed fluctuation under the proposed ANTSM+MESO controller is also smaller. The starting responses are depicted by Figure 8. One can undoubtedly observe that the speed overshoot of the proposed ANTSM+MESO controller is smaller than that under the ANTSM+ESO. Additionally, the time for the q-axis and a-phase currents to achieve the system stability was shorter than that under the ANTSM+ESO controller.
To further validate the availability of the proposed controller, numerous additional experiments were carried out. The moment of inertia has a straightforward impact on the starting and braking performance of the motor. As a result, the controller performance was tested by changing the value of inertia in the presented ANTSM+MESO controller. The inertia J=(1/3)J0, J=(1/2)J0 and J=J0 were chosen for comparative experiments. Figure 9 shows the step speed responses at the three different inertia. The sudden load change responses at the speed of 500 rpm are exhibited by Figure 10. As can be seen in Figures 9 and 10, the inertia mismatch imposes an impact on the stable operation of the motor. Nevertheless, the system can still operate stably under the proposed ANTSM+MESO controller.
The experimental results of speed, current iq and current ia during the speed change are shown in Figure 11(a). The anti-disturbance property of the ANTSM + MESO control strategy at 500 rpm is exhibited in Figure 11(b). From Figure 11, one can summarize that the ANTSM + MESO algorithm can better control the motor operation at a wide range of speed.
In this paper, a novel MESO-based ANTSM controller was constructed to improve the anti-disturbance performance of the PMSM drive system with parameter variation and unknown disturbance. To prevent the unsatisfactory control effect due to overestimating switching gain, an adaptive law was combined with the traditional NTSM strategy to achieve the expected performance. Furthermore, compensating the disturbance estimation value obtained by MESO to the ANTSM controller, the switching gain can be further reduced. Comprehensive experimental results demonstrate that the property of the MESO-based ANTSM algorithm outperforms both traditional PI and NTSM control methods. In future work, we will work on solving the stability problem caused by parameter variations.
