摘要：由于电机参数变化和负载扰动等不确定性因素的影响，永磁同步电机位置控制的动态响应和抗扰动能力不能很好的兼顾，本文提出一种基于滑模自抗扰控制器的永磁同步电机位置环控制策略，把转动惯量和负载作为扰动量，以电机转子角度为状态变量，通过扩展状态观测器观测，进行补偿校正，为高频抖振提供旁路，设计了滑模面和滑模控制律，提高了系统的稳定性。仿真表明，系统具有动态响应快，控制精度高，且系统对干扰具有很强的鲁棒性。

Abstract: Because of the affections from uncertainties motor parameter variations and load disturbances, the dynamic response and disturbance rejection of the PMSM position loop control are not well balanced. This paper presented a position loop control strategy of permanent magnet synchronous motor system based on sliding mode ADRC. Taking the moment of inertia and the load as a disturbance, and taking the rotor angle as state variables, which were observed and used to make compensation correction, provided a bypass for the highfrequency chattering by extending state observer. The sliding surface and sliding mode control law were designed, improving the stability of the system. Simulation results show that the system has a fast dynamic response, high precision control and the system has strong robustness for interferences.
