实际变结构控制系统的抖振削弱方法

Methods for Chattering Reduction in Practical Variable Structure Control Systems

变结构控制系统的抖振是影响变结构控制系统广泛应用的主要原因．在分析实际变结构控制系统的抖振的发生机理的基础上，讨论了抖振的消除和削弱途径．仿真结果表明：通过调整趋近规律的参数能达到良好的抖振削弱效果．

Chattering has been a main problem in application of variable structure control systems.We discuss the methods for chattering reduction after analysing the principles of chattering in practical variable structure control systems.The simulation results indicated that the approach rules presented is appropriate for chattering reduction.
