Abstract

An improved model-free nonsingular fast terminal sliding mode control (IMFNFTSMC) algorithm based on super-twisting extended sliding mode disturbance observer (STESMDO) is proposed to address the problems of control performance degradation and system failure of surface-mounted permanent magnet synchronous motor (SPMSM) under complex operating conditions. Firstly, the mathematical model of SPMSM under parameter ingestion is established; secondly, a novel hyperlocal model is proposed to combine with variable exponential approach law and the nonsingular fast terminal sliding mode (NFTSM) surface to design the speed-loop IMFNFTSM controller to accelerate the system convergence while reducing the sliding mode jitter. To enhance the control accuracy, the super-twisting extended sliding mode disturbance observer (STESMDO) is designed to estimate and feed-forward compensate the system disturbance. Finally, the effectiveness and superiority of the designed algorithms are demonstrated by comparing the proposed method with PI and the conventional model-free nonsingular fast terminal sliding mode control algorithm (MFNFTSMC) through simulations and RT-Lab experiments.
