摘要
针对一类带有状态时滞和输入时滞的不确定奇异系统,利用Lyapunove稳定性,采用新的积分不等式方法,用线性矩阵不等式形式给出了系统鲁棒能稳和鲁棒H∞控制的时滞依赖条件,其保守性小于已有的结果.最后给出数值例子验证了结论的可行性和有效性.
The paper considers robust control problem for uncertain singular dynamic systems with time --varying delays in state and control input. Based on the proper lyapunov function and using a new integral inequality,delay-dependent robust stabilization criteria and robust control are proposed for such systems in terms of linear matrix inequality(LMI), which is less conservative than existing results. Finally, a numerical example is given to illustrate the feasibility of the designed method.
