Event-Triggered Inverse Control for Parametric Feedback Systems With Asymmetric Dead-Zone Input

In this paper, an event triggered control scheme is proposed for strict feedback nonlinear systems with dead-zone input, and external disturbance. In the threshold setting, inevitable measurement interference is considered and an unknown non-static threshold is constructed. Then, an error representation between the event triggered control signal and the conventional control signal is established at the output end of the dead-zone actuator. Of course, the unknown threshold disturbance and smooth inverse of dead-zone make it more difficulty. The Zone behavior analysis is established to address the existence of this unknown threshold disturbance. Compared to the linear approximation of dead-zone, the application of the smooth inverse makes this result effective for both symmetric and asymmetric dead-zone input.
