Robust finite-time H∞ control of switched systems and its applications: a dynamic event-triggered method.

This paper considers the problem of finite-time H ∞ control for switched systems under a dynamic event-triggered mechanism. In order to avoid frequent switching phenomenon and exclude Zeno behavior, discrete state information is used to construct a state-dependent switching law and a dynamic event-triggered mechanism. The event-triggered condition only needs to be detected at the sampled instants, so the data transmission pressure is greatly relieved. By introducing a delay-dependent Lyapunov function with the internal dynamic variable, a criterion is established to achieve the finite-time H ∞ performance. A set of dynamic event-triggered controllers and a state-dependent switching law are co-designed to reach desired behavior. An application example of the switched RLC system is offered to demonstrate the advantages of the acquired method. [ABSTRACT FROM AUTHOR]
