摘　　要：本文设计了基于Super-twisting滑模速度控制器的永磁同步电机直接转矩控制系统,仿真分析了参数变化对系统输出特性的影响,分析结果表明,采用Super-twisting滑模速度控制器的永磁同步电机直接转矩控制系统比采用PI速度控制器的永磁同步电机直接转矩控制系统的鲁棒性强。The direct torque control system of permanent magnet synchronous motor based on super twisting sliding mode speed controller is designed,and the influence of parameter change on the output characteristics of the system is simulated.The analysis results show that the direct torque control system of permanent magnet synchronous motor based on super twisting sliding mode speed co ntroller has stronger robustness than that of the direct torque control system of permanent magnet synchronous mo tor with PI direct torque control.
