Speed control of induction motors using a nonlinear auto-disturbance rejection controller

This paper presents a robust nonlinear auto-disturbance rejection controller for induction motor. This controller has been developed to obtain high steady-state speed accuracy in addition to high dynamic performance. It takes into account external disturbance, parameter variations and modeling uncertainty of induction motors. Real time implementation based on a floating-point DSP TMS320C30 is used to test the controller's performance. A good speed tracking performance with small overshoot and fast setting time is obtained.
