Abstract:The issue of robustly exponential stability for a class of uncertain multiple time-varying delay systems with controller failures and nonlinear perturbations is considered.A switched uncertain multi-delay system model is utilized to describe the considered systems.A switching approach based on the average dwell time is employed for the switched system.A delay-dependent sufficient condition for robustly exponential stability of the switched system is established in terms of linear matrix inequalities by using the switching method.It is proved theoretically that the resulting closed-loop system is robustly exponentially stable even if controller failures are encountered.The effectiveness of the proposed method is also demonstrated by simulation example.
