Abstract
This paper studies model reference adaptive control for switched linear systems
with large parametric uncertainties. An aggregate leakage approach is proposed
to develop a novel adaptive law, which overcomes the state-of-the-art
assumption of knowing the upper and lower bounds of the parameter uncertainty.
In addition, a switching law is developed based on mode-dependent average dwell
time scheme, which exploits the information of the known reference model for
every subsystem, i.e., average dwell time is realized in a subsystem sense.
Based on the proposed time-constraint scheme, switching signals that are less
conservative than those based on dwell time and average dwell time can be
designed. Global uniform ultimate boundedness of the closed-loop adaptive
switched system is guaranteed. Furthermore, the tracking error is shown to be
upper bounded and also an ultimate bound is presented. Simulations using NASA
GTM aircraft illustrate the proposed method.
