Robust Fault-tolerant Control for Uncertain Time-delay Large-scale Systems with Integral Quadratic Constraints Performance

针对一类不确定时滞大系统,研究执行器或传感器失效情况下的鲁棒容错控制。通过运用积分二次约束、线性矩阵不等式及Lyapunov函数的新分析方法,得到无摄动时滞大系统具有鲁棒容错控制的时滞依赖稳定性判据。通过推导获得不确定时滞大系统的时滞依赖稳定性判据,设计鲁棒容错控制器。

Robust fault-tolerant control is presented for a class of uncertain time-delay large-scale systems in this paper.The robust fault-tolerant Control for sensor or actuator are studied.At first,a delay-dependent stability criterion for time-delay large-scale systems without perturbations is obtained through a new method based on integral quadratic constraints（IQC） performance,linear matrix inequality（LMI） and Lyapunov function.Next,a criterion for uncertain time-delay large-scale systems is obtained via derivations.At the same time,Robust fault-tolerant controller is designed.
