滑模变结构控制理论研究综述

针对近年来滑模变结构控制理论的应用与发展,从4个方面对其进行了分析和总结。讨论了滑模变结构的两个设计问题,即滑模面设计和求解控制律的滑模到达条件,以及如何消除滑模变结构的抖振问题;指明了滑模变结构的一个重要发展方向—离散滑模变结构控制。介绍了目前各个方面的研究内容和方法,对各种方法的优缺点进行了评述,特别介绍了与模糊控制、神经网络等其他控制方法相结合的研究方法,预期了今后的发展方向。

Overview of Sliding Mode Variable Structure Control

The application and further development of sliding mode variable structure control(SMVSC)are introduced in four aspects.Two basic problems of SMVSC are raised,i.e.designing of the sliding mode surface and conditions of solving control law.Then methods of reducing or eliminating chattering of SMVSC are analyzed.Finally one of the future research tendencies,i.e.discrete-time sliding mode variable structure control,is discussed.Recent research approaches of SMVSC are presented.The advantages,disadvantages and possible developing tendencies are commented,and the approaches combining with other control methods,such as fuzzy control,neural network control,are introduced.The trend of research in the future is prospected.
