Abstract
En 中文
This article studies the event-triggered (ET) adaptive output feedback control problem for switched nonlinear time-delay systems with unknown measurement sensitivity under asynchronous switching. A new adaptive dual-domination approach, which includes a constant gain and a dynamic gain, is proposed to compensate for the unknown growth rate and measurement sensitivity. A dynamic gain-based switched linear observer is introduced to estimate the unmeasured state. A suitable Lyapunov-Krasovskii function (LKF) is adopted to address the trouble caused by time-varying delay. Then, based on the average dwell time (ADT), a novel ET control strategy is established, which can address the problem of asynchronous switching between subsystems and the corresponding triggering controllers, while also ensuring the boundedness of all the closed-loop signals and eliminating the Zeno phenomenon. Finally, two examples are given to verify the validity of the developed control strategy.
