摘要
讨论一类线性不确定多时滞系统的鲁棒容错控制问题。基于Lyapunov稳定性理论和线性矩阵不等式方法(LMI),针对一类参数有界不确定多时滞系统,给出了状态反馈鲁棒容错控制器设计方法,并且利用该方法得到的闭环控制系统,不仅在执行器失效情况下具有渐进稳定性,对参数不确定也具有良好的鲁棒性。最后,应用设计实例及仿真结果验证该设计方法的可靠性和有效性。
The robust fault-tolerant control for linear uncertain systems with multi-time delay was discussed; and based on Lyapunov stability and linear matrix inequality,a design method of state feedback and robust fault-tolerant controller was presented for uncertain multi-time delay systems.The closed-loop control system based on this design method can have asymptotical stability against actuator failures and robustness against parameter uncertainties.Both design examples and simulation results verify the feasibility and the effectiveness of this proposed method.
