Model-based event-triggered tracking control of linear systems

This paper researches the tracking problem of linear systems with disturbances where output reference signals are generated by a linear stable exosystem. The model-based event-triggered control scheme is proposed, which not only renders the closed-loop system to be input-to-output stable (IOS) from the tracking signal to the output tracking error but also reduces the resource utilization to some extent. To guarantee the positive lower bound of inter-event times, the hybrid system model approach is adopted, in which the event-triggered mechanism is evaluated only after a certain amount of time elapsed from the last transmission. Finally, a numerical example is given to illustrate the efficiency and feasibility of the obtained results.
