摘要
研究了时滞不确定系统的D稳定性问题 .当系统参数在某一确定的区间变化时 ,该控制器能保证闭环系统的正则性、因果性和D稳定性 .利用线性矩阵不等式 (LMI)的解给出了控制器的设计方法 .
D stability of uncertain discrete-time systems with time delay was studied. When the parameters were assumed to be time-varying within a certain interval matrices, the controller guaranteed that the closed -loop system was regular, causal and D stable. The explicit formula of desired controller was provided by using the solution to the linear matrix inequalities(LMI). The numerical simulation result was provided to demonstrate the effectiveness of the presented method.
