摘　　要：建立伺服系统的摩擦模型,针对高精度伺服系统易受测量延迟及测量噪声等不确定性干扰因素的影响,提出基于模糊切换增益调节的变结构控制策略,并用Lyapunov方法分析了滑模控制的稳定性。最后通过仿真,证明该策略有效削弱了抖振,系统鲁棒性得到提高。The friction model of servo system is established. According to high accuracy servo system susceptible to uncertainty interference factors such as measure delay and measure noise etc., variable structure control strategy based on fuzzy-switching and gain-regulating is proposed. Then, the stability of sliding mode control is analyzed with Lyapunov method. Finally, the simulation results show the harmful buffeting has been reduced, and the system robustness has been improved.
