参数不确定性时滞系统的鲁棒H∞容错控制器设计

研究了一类同时具有参数不确定性、外界干扰和时滞的线性系统执行器失效的问题，给出了该系统一种鲁棒Ｈ∞容错控制器的失效执行器的输出信号是任意能量有界的干扰信号，不确定线性时滞系统的容错控制问题转化成了鲁棒Ｈ∞控制问题，控制器可以通过解修正的代数黎卡提方程得到，而且控制器与时滞常数无关，设计例子证明了所给方法的有效性。

Robust H∞ Fault-Tolerant Controller Design for Linear Delay Systems with Uncertainty

A methodology to design robust H∞ fault-tolerant controller for linear delay systems with uncertainty is developed. By assuming the output of fault actuator to be any arbitrary energy-bounded signal, the fault-tolerant control problem of linear delay systems with uncertainty is transformed into the problem of H∞ control. The controller is delay-independent and can be obtained by solving a modified Riccati equation. A design example s hows the effectiveness of the obtained approach.
