Event-triggered stabilization of uncertain switched linear systems under finite feedback bit rate

This paper investigates event-triggered stabilization of uncertain switched linear systems under finite feedback bit rate where the boundary of model uncertainty is unknown. Based on the appropriate boundary estimation, a novel communication and control strategy is given to obtain qualified feedback gains and visible system states in which the event-triggering mechanism is adopted. By utilizing the additional timing information carried by the triggering moments, the proposed event-triggering controller can achieve a lower occupation of average bit rate to ensure exponential convergence of the system state. Simulation results show the effectiveness of our method.
