摘要
介绍了一种基于指数趋近率的滑模变结构控制(SMC)方法。速度环采用PI控制,消除系统稳态误差和提高响应速度,位置环采用滑模控制,抑制参数摄动及负载扰动。仿真结果表明:该控制策略具有良好的响应速度并能快速准确的跟踪位置给定。
A sliding mode control (SMC) approach,which is based on exponential reaching law,was introduced. PI controller of velocity loop was introduced to reduce system steady-state error and to increase system response speed, the sliding mode controller of positional loop was applied to restrain effects of parameter uncertainties and external disturbance. The simulation results show that the controller is of good response speed and able to track the given position quickly and accurately.
