On the robust two-stage linear feedback control of the induction motor

In this article, we propose a linear, total active disturbance rejection, two stage, observer-based linear feedback control approach for the angular velocity trajectory tracking task and flux magnitude regulation in an induction motor system. Experimental results and comparisons with other established controller design methodologies are provided. The effectiveness, and robustness, of the proposed control schemes are tested under unknown loads generated by a coupled DC motor, whose armature current is made to track a chaotic system output thus generating a time-varying load torque.
