Model reference adaptive control of discrete-time piecewise linear systems

摘要

This article presents a switched model reference adaptive controller for discrete-time piecewise linear systems.\udIn the spirit of the work by Landau in the late seventies, proof of asymptotic stability of the closed-loop error system is obtained, recasting its dynamics as a feedback system and showing the feedforward and the feedback paths are both passive. The challenge is that both paths can be piecewise linear. Numerical results\udshow excellent performance of the proposed controller even in the face of sudden variations of the plant parameters.
