摘要
针对基于执行器容错的不确定奇异时滞系统,设计了对数量化控制器.使用Wirtinger不等式来降低保守性,通过求解线性矩阵不等式得到了充分条件,使得闭环系统不仅是渐进稳定的,而且满足一个无源性能指标,并给出控制增益矩阵求法.数值算例验证了方法的可行性和优越性.
A logarithmic quantized controller was designed for uncertain singular time-delay systems based on actuator fault tolerance.Wirtinger inequality was used to reduce the conservatism.Sufficient conditions were obtained by solving linear matrix inequalities,so that the closed-loop system was not only asymptotically stable,but also satisfied a passive performance index.The method of calculating the control gain matrix was given.The numerical example verified the feasibility and superiority of the method.
