不确定离散时滞大系统的滑模控制

摘要

This paper considers the problems of sliding mode control for uncertain discrete -time large-scale systems with delays .The system has time varying and uncertainty , which satisfies the norm bounded condi-tion.The sliding-mode surface is designed by LMI apptoach .Then the sliding mode controller design ap-proach is obtained .The conservative feature is overcame in the traditional sliding mode control approach which needs matched uncertainty .%研究了不确定离散时滞大系统的滑模控制问题. 在系统不确定性满足范数有界的条件下,利用线性矩阵不等式的方法设计滑模面,给出滑模控制器设计方法,从而克服了需要满足匹配条件的传统滑模控制方法的保守性.
