摘  要：针对永磁同步电动机(PMSM)伺服系统的非线性，提出了一种基于自适应模糊算法的滑模控制器。控制器利用模糊控制克服模型不精确的影响，利用自适应控制产生滑动模态并削弱滑模控制带来的抖振。将此控制器用于永磁同步电机伺服系统的位置控制，仿真对比研究和电机实际运行结果表明，此控制策略可行，且对负载扰动等不确定性具有很好的鲁棒性。

Abstract:This paper presented an adaptive fuzzy sliding mode controller of nonlinearity and uncertainty for permanent magnet synchronous motors(PMSM)servo system.This controller made use of fuzzy control to assign compensate according to expert’s experience,and adaptive control to attenuate chattering caused by sliding mode.This method was applied to position control of the PMSM servo system.Simulation and experiment results verified the validity and robustness against uncertainties of load disturbance.
