Adaptive regulation of a class of nonlinear systems with unknown sinusoidal disturbances

Abstract

This chapter addresses adaptive output regulation for a class of nonlinear systems with sinusoidal disturbances. The gain matrix of the sinusoidal disturbances depend the system output. The disturbances undertaken are unmatched. The chapter presents a new method for estimating sinusoidal disturbances. Based on the estimation method, a method of adaptive output regulation is presented, which can guarantee that all the signals in the closed loop are bounded and the output converges to zero. © 2012 Springer Science+Business Media B.V.
