摘　　要：研究了带有时滞和不确定的非线性系统的鲁棒控制问题。首先,利用积分公式将时滞系统转化为无时滞系统,结合Lyapunov泛函法和稳定性理论,给出了一个鲁棒稳定的设计方法和该控制系统鲁棒稳定的充分条件,最后利用可解线性矩阵不等式给出控制器的设计方案。The paper is concerned with the robust control based on observer for uncertain nonlinear time - delay systems. First, the delay systems into nodelay systems by using the integral equation. Based on that, a method for designing the robust stability controllers is presented. And by Lyapunov function and LMIS a sufficient condition for the systems robust stabilization and method of its controllers design are offered.
