An adaptive controller for abruptly changing MIMO systems with nonlinear model uncertainties

A novel adaptive control algorithm for deterministic unknown abruptly changing MIMO (multi-input multiple output) systems subject to nonlinear model uncertainties is presented. A fast parameter tracking algorithm and pole-assignment calculation are included in the proposed controller. It is shown that all the variables in the closed-loop system are uniformly bounded if the linear bound of the nonlinear model uncertainties is comparatively small.<
