摘　　要：以线性不确定时滞系统为模型,应用李雅普诺夫稳定性理论和LMI工具箱,采用状态反馈控制器设计连续系统的容错控制器,研究了线性不确定时滞连续系统的状态反馈鲁棒稳定问题。给出了系统在执行器失效情况下渐近稳定的充分条件及相应的状态反馈鲁棒容错控制器的设计方法,仿真结果验证了该方法的可靠性和有效性。The problems of state feedback robust stability for linear uncertain time-delay system with state delay are studied by using linear matrix inequality and Lyapunov stability theory with the model of the linear uncertain time-delay system. The sufficient conditions for the system to be asymptotically stable against actuator failures are presented and the corresponding design method of robust fault-tolerant control laws by state feedback is provided. An illustrative example is given to illustrate the obtained results, it verifies the feasibility and effectiveness of the proposed methods.
