Event-Triggered H∞ Tracking Control for Switched LPV Systems

In the paper, H
_∞
tracking control for continuous-time switched linear parameter varying (LPV) systems based on event-triggered mechanism is investigated. A sufficient condition on how to co-design the event generator and the switching LPV tracking controller to achieve the H
_∞
tracking performance is presented. Both the event generator and the switching controller are parameter-dependent. In order to avoid the Zeno phenomenon, we prove that the lower bound of our proposed inter-event interval is strictly positive. Finally, a numerical simulation result shows the feasibility and effectiveness of our method. The result indicates that our method can not only realize the the H
_∞
tracking control of the reference model, but also can decrease energy consumption.
