Shunt Output Feedback Adaptive Controllers for Nonlinear Plants

Abstract The method of parallel feedforward compensator ("shunt") developed earlier for adaptive control of linear plants is extended to a class of nonlinear minimum phase plants. The new output feedback adaptive controllers achieve global stability of the closed loop system for regulation and tracking problems. The total order of the proposed controller is equal to the relative degree of the plant.
