Abstract :
A nonlinear auto-disturbance rejection controller (ADRC) has been developed to ensure high dynamic performance in this paper. By using the extended state observer (ESO), ADRC can estimate accurately the derivative signals and accurate decoupling of induction motor is achieved too. In addition, the proposed strategy doesn´t require knowledge of induction motor parameters. The simulation and experiment results show that the controller operates quite robustly under modeling uncertainty and external disturbance, and it is concluded that the proposed topology produces better dynamic performance such as small overshoot and fast transient time in the speed control than classical PID controller
