Active disturbance rejection control for uncertain time-delay nonlinear systems

Active disturbance rejection control for uncertain time-delay nonlinear systems

This paper addresses the problems of design and analysis of active disturbance rejection control (ADRC) for uncertain nonlinear systems subject to input time-delay. A novel extended state observer (ESO) is first designed as a predictor to realize the predictive state, and the total uncertainty which...
