不确定多时滞系统的输出滑模控制

Output Variable Structure Control for Systems with Mismatched Uncertainty and Multiple Delays

本文研究了带有不匹配参量不确定性和匹配外扰的多时滞系统的鲁棒滑模控制。当状态不可量测时,利用系统输出设计滑模面,通过线性矩阵不等式给出了滑模面存在的一个时滞无关充分性条件,在此基础上设计变结构控制律,实现滑模控制。最后通过仿真说明该控制策略的有效性。

This note is devoted to robust sliding-mode control for multiple time-delay systems with mismatched parametric uncertainties. A delay-independent sufficient condition for the existence of linear output-feedback sliding surfaces is given in terms of linear matrix inequalities, Based on which the corresponding reaching motion controller is also developed. The results are illustrated by an example.
