摘要：
The problem of delay-dependent non-fragile H∞ control for uncertain discrete-delay systems is investigated. Based on an inequality method for finite sums, a delay-dependent boundary real lemma is obtained by using the Lyapunov-Krasovskii stability theory, which can ensure that the closed-loop system is internally stable with a given H∞ disturbance attenuation level via a non-fragile controller. Then the design of non-fragile H∞ controller is proposed by using iterative algorithm to additional and multiplicative uncertain cases. Linear matrix inequalities (LMI) in Matlab toolbox is applied to get the solution easily. Finally, a numerical simulation shows the effectiveness of this approach.
