摘要
针对低速摩擦伺服系统,提出采用指数趋近率的滑模控制方法,以保证运动点在有限时间到达平衡点,缩短了趋近时间。并且通过引入饱和函数以削弱抖振。最后运用Matlab/Simulink软件平台仿真,验证了该方法具有良好的跟踪特性和较强的鲁棒性。
Aiming at the low-speed friction servo system,a design method of sliding-mode control using exponential approach law is presented to drive the system to reach the equilibrium point in finite time so that this can shorten the appulsive time. And the design can weaken chattering phenomenon due to the adduction of the saturated function. At last, based on the Matlab/Simulink platform,Simulink indicates that the control method improves the tracking accuracy considerably and is robust.
