Summary This article discusses the problem of global output feedback control for a class of uncertain nonlinear systems. Based on dynamic gain method and adding one power integrator, a new system design scheme is proposed to derive the adaptive output feedback controller such that the system state asymptotically converges to the origin. A numerical simulation and a practical example are presented to show the effectiveness of the proposed method.
