Application and Optimize Design of Active Disturbance Rejection Controller

Active disturbance rejection controller (ADRC) is a new type of nonlinear controller for estimating and compensating the uncertainties system.Based on studying deeply and systemically the theory of ADRC,the optimization active disturbance rejection controller was established by means of linearization of the nonlinear system and parameter conformity,then a new regulation of parameters for the ADRC was proposed.Simulation results showed that the regulation of parameters is simple and the parameter'number is greatly reduced while the performance of the controller is not influenced,and the system has good robustness and desirable control effect.
