In this paper, a novel super-twisting resonant controller with a fixed-time adaptive law (FTAL-STRC) is proposed to improve robustness and current smoothness of permanent magnet synchronous motor (PMSM). Firstly, the STRC controller is proposed, which incorporates the benefits of both the super-twisting controller (STC) and the quasi-resonant controller (QRC). Compared to the universal proportional integral resonant (PIR) control method, the proposed STRC can decrease the influence of inverter nonlinearity, and improve the robustness to parameters change, simultaneously. Secondly, an adaptive law based on fixed-time convergence theory (FTAL) is proposed to further compensate for the unknown disturbance, and realize fast tracking. Then, the composite control strategy is developed. Meanwhile, the stability of the proposed FTAL-STRC is proved rigorously. Finally, simulations and experiments are conducted to validate the effectiveness of the proposed method.

This paper rigorously addresses the intricate control demands of high-speed, high-pressure, wide adjustable speed range, and high energy utilization efficiency required in hydrogen fuel cell centrifugal compressor, with a focus on the speed control of 40,000 RPM permanent magnet synchronous motors (PMSMs). An improved second-order super twisting sliding mode control (STSMC) strategy is proposed to enhance system stability and robustness by integrating the beetle antennae search (BAS) algorithm and grey wolf optimization (GWO) algorithm. The global search capability of BAS is used to improve the local optima issues of GWO, and then the improved GWO algorithm is utilized to address the issues related to parameter selection and convergence speed inherent in the STSMC. Theoretical validity of the proposed strategy is asserted through Quadratic Lyapunov Function, and its practicality is affirmed by thorough simulation. Comparative analyses are conducted with PI controller, traditional Sliding Mode Controller (SMC), and standard supertwisting Sliding Mode Controller (ST) under several case studies to show the superiority of the propose STSMC.

GVF-based guidance and super-twisting control of autonomous surface vehicle for target tracking in obstacle environments with experiments

This paper addresses the target tracking problem of an under-actuated autonomous surface vehicle (ASV) subject to internal uncertainties and exogenous forces in ocean environments with static and dynamic obstacles. A collision-free target tracking (CFTT) control method is proposed based on a guiding vector field (GVF) guidance and a super-twisting algorithm (STA) control. Specifically, a resultant GVF is developed to guide the ASV towards the target position and to avoid multiple obstacles. Based on the resultant GVF, a saturated guidance law is designed to calculate the surge velocity and angular velocity commands. Then, robust exact differentiator (RED)-based observers are developed to estimate the lumped disturbances within finite time. By using the estimated lumped disturbances, STA-based anti-disturbance kinetic control laws are designed to track the given velocity commands within finite time. The finite-time input-to-state stability of the closed-loop system is proven based on cascade theory. Emulational and experimental validations are conducted to substantiate the efficacy of the proposed CFTT control method.

Aiming at the control system of permanent magnet synchronous servo motor which is easily affected by external disturbance and parameter uncertainty, a single neuron sliding mode combining single neuron adaptive algorithm and super-twisting sliding mode (STSM) control is proposed. The STSM control is used to overcome the chattering problem in the traditional sliding mode control, and the proportional control and the STSM control are combined to enhance the robustness of the control system. In order to improve the dynamic performance of the system and enhance the anti-disturbance ability of the system, the single neuron adaptive control adopted can adjust the relevant parameters of the designed sliding mode controller online. The simulation and experimental results show that the designed improved sliding mode controller can effectively suppress the chattering of the control system, realize the fast following and no overshoot of the control system, and enhance the robustness of the system.

Worst-case error bounds for the super-twisting differentiator in presence of measurement noise

引用

AUTOMATICA 2023年第1期152卷

作者： Seeber, Richard Graz Univ Technol Inst Automat & Control Christian Doppler Lab Model Based Control Complex Graz Austria

The super-twisting differentiator, also known as the first-order robust exact differentiator, is a well known sliding mode differentiator. In the absence of measurement noise, it achieves exact reconstruction of the time derivative of a function with bounded second derivative. This note proposes an upper bound for its worst-case differentiation error in the presence of bounded measurement noise, based on a novel Lipschitz continuous Lyapunov function. It is shown that the bound can be made arbitrarily tight and never exceeds the true worst-case differentiation error by more than a factor of two. A numerical simulation illustrates the results and also demonstrates the non-conservativeness of the proposed bound.(c) 2023 Elsevier Ltd. All rights reserved.

Improved high-order integral fast terminal sliding mode-based disturbance-observer for the tracking problem of PMSG in WECS

The present paper proposes a high-order sliding mode control approach for wind turbine (WT) with a permanent magnet synchronous generator (PMSG) under complex situations. The suggested control approach uses a disturbance observer (DO) with a modified super-twisting integral fast terminal sliding mode control (MSTIFTSMC) approach. The new developed method is specifically intended to ensure maximum power point tracking, track the state variables of the WT-PMSG, and enhance the quality of its output state variables. The strategy control is applied to the machine side converter (MSC) and grid side converter. In the MSC, DO combined with the MSTIFTSMC technique is designed for the rotor speed subsystem to attenuate the mechanical torque, which is considered an immeasurable disturbance. The proposed control technique based on DO: (i) ensures the convergence of the state variables of the WT-PMSG in finite-time;(ii) reduces the chattering issue in the sliding mode control (SMC);(iii) estimates mechanical torque then rejects them and compensates parametric uncertainties. To validate the tracking performance of the proposed control structure, three scenarios are presented with a comparison.

Prescribed-Time Sliding Mode Observer for Nonlinear Triangular Systems

This paper deals with the problem of prescribed-time sliding mode observer design for a class of triangular nonlinear systems. The contribution of the paper is twofold. First, we propose a new prescribed-time observer based on super-twisting-algorithm (STA), for a triangular two-dimensional system. Such an STA algorithm is based on the use of two power terms, instead of only one as with the standard STA. Then we exploit this algorithm to develop a novel step-by-step arbitrary order sliding mode observer for a general class of triangular systems. An application to vehicle motion estimation in a platoon is provided to show the validity and efficiency of the proposed step-by-step sliding mode observer. For this case study, we use a third-order longitudinal kinematic linear vehicle model.

A novel super-twisting control method is proposed for a class of third-order systems with matched Lipschitz disturbance in this paper. The proposed method ensures finite-time convergence to the fourth-order sliding set, by using a homogeneous, continuously differentiable and strict Lyapunov function. Finally, numerical simulation results are shown to illustrate the effectiveness of the proposed method.
