摘要
The normal H ∞ control design deals with both plant modeling uncertainties and exogenous signal uncertainties by constructing a controller which stabilizes uncertain li near systems while satisfying an H ∞ norm bound constraint on disturbance attenuation for all admissible uncertainties. However, the control design may result in unsatisfactory performances or even instabilities in the event of sensor failures in practical plants. This paper focuses on the problem of the design of robust reliable H ∞ control for a class of time varying uncertainty system with sensor failures. The paper presents a novel technique which deal with this problem by solving three linear matrix inequalities (LMIs). The strict proof guarantees the feasibility of this approach.
许多Ｈ∞控制设计是处理系统模型不确定性和外部信号不确定性的问题。然而在实际系统中，经常出现装置的传感器失效的情况，通常的Ｈ∞控制设计方法不能得到满意的性能，甚至造成系统不稳定。本文针对一类时变不确定性系统，在传感器故障情况下，提出了Ｈ∞控制器的一种设计方法。整个设计过程被简化为三个线性矩阵不等式（ＬＭＩｓ）来求解。严格的理论推导保证了方法的可行性。
