Abstract

Abstract: Based on the analysis for the disadvantage of the current discrete event-triggered communication schemes, a new kind of event-triggered communication scheme constrained by transient and stead-state process was proposed to perfect the conservatism and isolation of the fault-tolerant controller. A closed-loop failure model which was concerned with state-error was established for networked control system. Using the improved Wirtinger's inequality and the improved reciprocally convex combination inequality, the co-design between new event-triggered communication scheme and less conservative robust H_∞ fault-tolerant control for networked control systems was focused on. The simulation results show that the new discrete event-triggered communication scheme can save more network communication resource without deteriorating the system performance excessively. At the same time, the controller has less conservatism and becomes more easily to acquire. The triggering condition designed has a definite physical meaning and parameters are more likely to choose.
