不确定关联时滞大系统的鲁棒自适应控制

Adaptive robust control for uncertain large-scale time-delay systems

针对具有时滞的不确定关联大系统,研究了自适应状态反馈控制器的设计问题。当时滞常数未知时,给出了对未知时滞常数及不确定参数的自适应控制方案。建立了可由线性矩阵不等式(LMI)表示的镇定条件。最后给出了仿真示例以说明该方法的有效性。

In this paper, the issue of designing adaptive state feedback controller for a class of large-scale uncertain time-delay systems is considered. When the time-delay constant is not precisely known, the feedback control with adaptation to time-delay constant and uncertain parameters are given. Stabilization conditions in the form of linear matrix inequality （LMI） are established. An example is given to illustrate the effectiveness of the result.
