Output Feedback Regulation Control for a Class of Uncertain Nonlinear Systems

Abstract

This paper investigates the global regulation problem for a class of nonlinear systems with integral inputtostate stable (iISS) dynamic uncertainty. By designing a reducedorder observer, a systematic output feedback control strategy is proposed. The designed dynamic controller can achieve the global setpoint regulation control and guarantee all signals of the closedloop systems bounded. The developed control schemes find its application in the pendulum control system. Simulation results verify its effectiveness.
