Model reference adaptive control for switched LPV systems and its application

摘要

In this study, the problem of model reference adaptive control (MRAC) for switched linear parameter-varying (LPV) systems with parametric uncertainties is investigated. First, a switched LPV controller with the adaptive laws is designed. Then, the proposed LPV controller with the adaptive laws guarantees that all the closed-loop system signals remain bounded under a class of switching signals with average dwell time, and the state tracking error converges to a small ball centred at the origin whose radius can be made arbitrarily small by appropriately choosing the design parameters. Finally, a practical example about MRAC for a turbofan-engine is given to demonstrate the validity of the main results.
