摘　　要：对短时变时延下具有执行器故障的网络控制系统的鲁棒非脆弱保性能控制问题进行研究。为了降低保守性,利用标称点方法对系统进行建模,并结合时变故障矩阵与非脆弱控制,将连续时间系统模型转变为具有范数有界不确定参数的时变离散时间模型。根据Lyapunov对离散系统的稳定性判据以及线性矩阵不等式技术,给出保性能控制器的设计策略和相应的二次性能指标的求解方法,并通过算例验证了所提策略的正确性。In this paper,the problem of robust non-fragile guaranteed cost control for networked control sys-tems with actuator faults under short time-varying delay is studied.To lessen conservatism,the nominal point method is used to model the system,combined with time-varying fault matrix and non-fragile control.The continuous-time system model is transformed into a time-varying discrete-time system model with norm bounded uncertain parameters.According to Lyapunov's stability criterion for discrete systems and the linear matrix inequality technique,the design strategy of guaranteed cost controller and the solution method of corre-sponding quadratic performance index are given.An instance is proposed to confirm the correctness of the pre-sented strategy.
