Discrete Event-Triggered H∞ State-Feedback Control for Networked Control Systems

This paper is concerned with H-infinity controller design problem for event-triggered networked control systems with bounded time-varying transmission delay and packet losses. The state-feedback controller proposed in this paper deals with event-triggered model and guarantees a required disturbance attenuation level gamma subject to external bounded disturbances. Firstly, an improved event-triggered communication scheme is proposed. Secondly, an event-based system is transformed into a delay system. Thirdly, the asymptotical stability criterion in the sense of mean-square for the delay-dependent H-infinity control, and the collaborative approach of the state-feedback control gain and the event-triggered scheme parameters are derived by using LMIs technique and Lyapunov stability theory which lead to less conservatism. Finally, two examples are provided to illustrate the effectiveness of the proposed event-triggering transmission scheme and the co-design method.
