摘　　要：针对永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)位置伺服系统中存在摩擦甚至机械传动间隙等问题,传统PID控制已无法满足性能要求,故采用全局快速终端滑模控制(Global Fast Terminal Sliding Mode Control,GFTSMC)技术,设计了滑模控制器,提高PMSM位置跟踪性能,并使用Lyapunov理论证明其稳定性;同时针对系统存在外部干扰的问题,设计了干扰观测器(disturbance observer,DOB),提高系统的抗扰动能力。数字仿真结果显示,算法提高了PMSM控制系统的快速响应、高精度跟踪、鲁棒性等性能,证明了方法的有效性。Due to the friction and even mechanical transmission gap in position servo system of permanent magnet synchronous motor(PMSM),the traditional PID control can not meet the performance requirements.Therefore,global fast terminal sliding mode control(GFTSMC)technology was used to design sliding mode controller to improve position tracking performance of PMSM and the Lyapunov theory is used to prove its stability.At the same time,in view of the problem of external interference in the system,a disturbance observer(DOB)was designed to improve the anti-disturbance ability of the system.The numerical simulation results show that this algorithm could improve the performance of PMSM control system involving fast response,high precision tracking and robustness,so that the effectiveness of the proposed method is proved.
