This paper concentrates on bipartite formation control for nonlinear leader-following multi-agent systems (MASs) with fixed and switching topologies under aperiodic Denial-of-Service (DoS) attacks. Firstly, distributed control protocols are proposed under the aperiodic DoS attacks based on fixed and switching topologies. Then, considering control gains, as well as attack frequency and attack length ratio of the aperiodic DoS attacks, using algebraic graph theory and the Lyapunov stability method, some criteria are acquired to ensure that the nonlinear leader-following MASs with either fixed or switching topologies can realize bipartite formation under aperiodic DoS attacks. Finally, numerical simulations are carried out to validate the correctness of the theoretical results.

“…Therefore, numerous studies devoted to developing appropriate control techniques in the field of PMSMs have been carried out [ 7 ]. Several nonlinear control methods have been proposed and implemented, e.g., active disturbance rejection control [ 8 , 9 ], predictive current control [ 10 ], internal model control [ 11 ], and sliding mode control (SMC) [ 12 ]. Among these modern control methods, SMC is a popular and effective strategy for nonlinear systems with disturbances due to its benefits like quick response, small overshoot, and strong disturbance rejection ability [ 13 ].…”

This paper focuses on the speed control of a permanent magnet synchronous motor (PMSM) for electric drives with model uncertainties and external disturbances. Conventional sliding mode control (CSMC) can only converge asymptotically in the infinite domain and will cause unacceptable sliding mode chattering. To improve the performance of the PMSM speed loop in terms of response speed, tracking accuracy, and robustness, a hybrid control strategy for a fixed-time-convergent sliding mode controller (FSMC) with a fixed-time-convergent sliding mode observer (FSMO) is proposed for PMSM speed regulation using the fixed-time control theory. Firstly, the FSMC is proposed to improve the convergence speed and robustness of the speed loop, which can converge to the origin within a fixed time independent of the initial conditions. Then, the FSMO is used as a compensator to further enhance the robustness of the speed loop and attenuate sliding mode chattering. Finally, simulation and experimental results show that the proposed method can effectively improve the dynamic performance and robustness of the PMSM speed control system.

“…Similarly, [10] presented an event-triggered TSMC to regulate the speed of the PMSM with the primary goal of improving speed control performance and reducing chattering. In [11], an action integral was added to TSMC to enhance the dynamic performance of speed tracking under torque ripple and external disturbance. Paper [12] proposed a second-order TSMC to obtain a fast convergence and reduce the chattering phenomena.…”

This letter investigates real-time implementation of a finite-time control for permanent magnet synchronous motors in the presence of external load disturbance. Firstly, an integral terminal sliding manifold is designed to achieve fast speed, high precision performance, and to enhance the quality of currents by reducing the total harmonic distortion. Indeed, the proposed surface manifold ensures a finite-time convergence of the speed state variable. Secondly, a switching control scheme is added for the system control to force the state systems to converge to their desired values in the presence of load disturbance. Finitetime stability is proved based on Lyapunov theory. Finally, the effectiveness of the designed controller is validated by carrying out real-time experimental studies using eZdspTM F28335 board. According to the experimental results, the proposed controller is easy to implement, improves tracking accuracy, reduces the chattering issues and ensures robustness against external load disturbance.
