Non-fragile guaranteed cost control for networked control systems with actuator faults
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.
