Adaptive Dynamic Surface Control for Disturbance Attenuation of Nonlinear Systems

Sung Jin Yoo, Jin Bae Park*, and Yoon Ho Choi

Abstract

This paper proposes an adaptive dynamic surface control (DSC) approach for disturbance attenuation of uncertain nonlinear systems in the parametric strict-feedback form. In the proposed control system, a smooth projection algorithm is employed to train uncertain parameters. The proposed DSC system can overcome the complexity of an actual controller caused by the recursive differentiation of virtual controllers and parameter adaptation laws in the backstepping design procedure. From Lyapunov stability analysis, it is shown that the proposed controller has H∞ tracking performance to attenuate external disturbances

Keywords Adaptive control, aircraft wing rock motion, disturbance attenuation, dynamic surface control.
