摘要：
In this paper, an active disturbance rejection control (ADRC) scheme is proposed for a nonlinear system subjected to actuator saturation via a delta operator approach. A delta-domain extended state observer (ESO) with an anti-windup compensator is designed to estimate the states and the nonlinear term. Then, a ESO-based composite controller is developed so as to control the nonlinear delta operator system. Finally, the sufficient conditions to guarantee the convergence of the delta-domain ESO and the overall controlled system are provided in common.
