计算机滑模变结构控制的切换函数超前补偿

Computer Sliding Model Control With Forward Compensation for Switching Function

本文分析了计算机滑漠变结构控制系统采样周期和计算时间的存在所导致的颤振现象，提出了一种削弱其额振幅值的方法─—切换函数超前补偿法。理论分析和仿真结果均表明了这种方法的有效性和可行性。

This paper analyzes the chattering problem in computer sliding mode control system caused by its sampling cycle and calculating time. A method called forward compensation for switching function is suggested and proven to be effective and feasible by theory analysis and computer simulation.
