Observer-Based Event-Triggered H Control for Singular Systems with Unknown Disturbances

Journal Article


Abstract


  • The purpose of this paper is to study the event-triggered H∞ control problem of network singular systems with unknown disturbances. First, we use an adaptive event-triggered scheme suitable for singular systems, which can adaptively adjust the trigger parameters of dynamic errors in order to economize confined network resources and downgrade conservatism. In this paper, the singular system is taken as the controlled object, and two observers are designed to assess the state and disturbance of the system, respectively. Therefore, a novel adaptive event-triggered H∞ control for singular systems with extended state observer is proposed. Second, by constructing a new Lyapunov functional, and using linear matrix inequalities and the theory of Lyapunov stability, the conditions for the system's asymptotic stability are obtained. Finally, to demonstrate the validity of the derived results, some simulations and comparisons are provided.
