This paper investigates the global regulation problem for a class of nonlinear systems with integral input-to-state stable (iISS) dynamic uncertainty. By designing a reduced-order observer, a systematic output feedback control strategy is proposed. The designed dynamic controller can achieve the global set-point regulation control and guarantee all signals of the closed-loop systems bounded. The developed control schemes find its application in the pendulum control system. Simulation results verify its effectiveness.
