Output-based dynamic event-triggering control for sensor saturated systems with external disturbance

摘要

In this paper, the dynamic event-triggering output feedback H∞ controller is constructed for sensor saturated systems with external disturbance. Motivated by the limited transmission resources and feasibility of engineering realization, we consider the situation where the outputs of sensor and controller are transmitted asynchronously based on two independent dynamic event-triggering strategies, which can generate fewer numbers of triggering compared with the static one and make more sense for engineering implementation in the asynchronous form. Zeno phenomenon can be efficiently eliminated due to the compulsive dwell time under our proposed triggering conditions. Moreover, the emulation-based approach and co-design approach for the controller and triggering condition are separately presented, both of which can achieve local L2 stability and asymptotic stability for sensor saturated systems with/without external disturbance. Finally, an example of F-8 aircraft is employed to testify the validity of the proposed method.
