Speed Regulation for PMSM Based on Fixed-time Sliding Mode Control

Abstract

This paper mainly studies the control problem of permanent magnet synchronous motor (PMSM) speed control system. Firstly, by analyzing the error dynamics equation of PMSM, an appropriate integral fixed-time sliding mode surface is selected. Then, an integral fixed-time sliding mode control algorithm is designed through the selected integral sliding mode surface. Finally, comparison results of numerical simulations are provided to verify the effectiveness of the proposed control method.
