Adaptive Regulation of Nonlinear Systems by Output Feedback

Abstract

In this paper adaptive regulation by output feedback is considered for a class of single-input/single-output nonlinear systems described by multiple linear models. The adaptive laws are based on the filtered state and input of an adaptive observer. Then a controller is given by a state-dependent Riccati equation, which assures the stability of the adaptive system. Simulation results are given to illustrate the theory.
