摘要/Abstract：
A novel hybrid control algorithm is proposed in this paper to optimize the performance of the speed control system of permanent magnet synchronous motors(PMSM), allowing it to maintain ideal speed even under external disturbances and torque pulsations. Firstly, a new sliding mode reaching law(NSMRL) is presented and combined with a fast integral terminal sliding mode surface to reduce the system’s convergence time without increasing the system’s chattering. Secondly, the sliding mode control algorithm is combined with a high-gain disturbance observer based on iterative learning control(ILC-HGO) algorithm to enhance the system’s anti-disturbance capability. The stability of the proposed algorithm is theoretically analyzed using the Lyapunov method. Finally, MATLAB simulations are conducted to validate the proposed algorithm’s superiority over traditional algorithms, with faster convergence speed, smaller overshoot, and better robustness.
