Composite nonlinear feedback event‐triggered control of switched system with input saturation

Abstract

This paper focuses on the composite nonlinear feedback (CNF) event‐triggered control of saturated switched systems. The proposed CNF event‐triggered control method can not only improve transient performance of systems but also decrease network bandwidth consumption. Here it is worth emphasizing that this event‐triggered mechanism is presented based on the inherent characteristics of CNF control and switched systems. Whether to sample the current state of system is determined by the specialized event‐triggered condition, and under this triggering condition, we obtain the practical stability of saturated switched systems via multiple Lyapunov functions method. Switching signal satisfies dwell time constraint. The proposed method can avoid Zeno behavior, and the specific proof has been provided. In addition, an example of turbofan engine model verifies the feasibility and effectiveness of the given method.
