摘要
研究范数有界参数扰动的不确定线性系统的鲁棒容错控制问题。基于Lyapunov稳定性理论,针对不确定线性系统存在执行器失效情况,分别应用Riccati不等式和LMI(Linear Matrix Inequation)两种方法给出了闭环系统具有完整性的充分条件。并应用LMI给出了线性不确定系统对执行器失效具有容错性和完整性的设计步骤。
It is concerned with robust fault-tolerant control for a class of uncertain linear systems with norm-bounded parameter perturbations. As for fault actuator of uncertain systems, based on Lyapunov asymptotic stability theory, by means of Riccati inequality and LMI (linear matrix inequality) respectively, the sufficient conditions are given for closed-loop systems possessing integrity. In terms of LMI, the design method of controller for uncertain linear system possessing integrity against actuator failure is presented.
