| 摘 要： | 针对时变时滞不确定采样系统,研究了时滞依赖的鲁棒镇定控制器设计问题。通过引入一个自由变量,得到了一个新的具有更低保守性的Lyapunov渐近稳定判据。利用该判据,采用线性矩阵不等式技术推导了此类系统的时滞依赖鲁棒镇定控制器存在的充分条件。数值算例验证结果表明所提出的算法比已有的设计方法具有较低的保守性。

| Abstract: | Problem of robust stabilization for uncertain sampled-data systems with time-varying delay was studied.Through introducing a free variable,a new Lyapunov asymptotical stability criterion with less conservativeness was established.Based on the criterion,delay-dependent sufficient conditions on robust stabilization for the systems were obtained by using linear matrix inequality technique.Compared with a previous result,one example was provided to show the reduced conservatism of the proposed approach. |
