摘　　要：在伺服电动机控制系统的使用中,由于电动机存在端部效应引起的动子磁链非正弦性、摩擦非线性以及负载的变化等都将使高精度位置伺服系统性能变坏,因此必须采用鲁棒性强的控制策略来抑制这些扰动。本文设计了一种带积分滑模面的自适应模糊滑模控制系统,并将其应用于伺服电动机的位置控制系统中。自适应模糊滑模控制系统由模糊控制和切换控制组成,运用模糊控制器来模拟反馈线性化控制率,使用切换控制来补偿滑模控制器的输出误差。调节算法是从李雅普洛夫稳定性理论得到的,从而可以保证系统的稳定性。经仿真验证,所设计的系统性能令人满意,而且对参数变化和外部负载扰动具有较强的鲁棒性。In the use of servo motor control system,some characteristics of motor,such as non-sinusoidal flux of motor mover caused by end effect,nonlinear friction,will make the effects of the servo system bad.So we must use some control strategies with high robustness to suppress these disturbance.In this paper,a design method of fuzzy sliding mode control system with adaptive integral sliding mode surface,and applied to the position control of servo motor system.Adaptive fuzzy sliding mode control system consists of fuzzy control and switching control,using fuzzy controller to simulate feedback linearization control rate,output error using the switching control to compensate the sliding mode controller.Control algorithm is derived from the Lyapunov stability theory,which can guarantee the stability of the system.Simulation results show that,the system performance is the satisfaction,and it’s robust with regard to the parameter variations and external load disturbance.
