摘　　要：为提高永磁同步电动机位置伺服系统的快速性和精确度,采用滑模变结构控制策略,由电机数学模型和位置检测方法推导出一种新的位置关系状态方程,据此设计位置滑模变结构控制器,降低了滑模控制的阶次,简化了控制器的设计。实验结果表明所设计的控制器位置响应快、无超调,有效地提高了伺服系统的动态性能。In order to improve the rapidity and accuracy of the permanent magnet synchronous motor position-servo system, the sliding mode variable structure control strategy was applied to the system. A new state equation of position was derived by position detection method and the PMSM mathematical model, the position sliding mode variable structure con- troller was designed on the equation to reduce the order of sliding mode control and simplify controller design. The experi- mental results show that the sliding mode position controller has rapid position response and no overshoot and effectively im- prove the dynamic performance of the servo system.
