The position control of induction motors using a binary disturbance observer
A control approach for the robust position control of an induction motor based on the binary disturbance observer is described. The binary controller with the binary disturbance observer is implemented for the position control of the induction machine subjected to load disturbances and realizes continuous control. The binary disturbance observer is used to eliminate the chattering problem of a sliding mode disturbance observer. In order to eliminate the steady-state error, the binary disturbance observer with an integral augmented switching hyperplane is proposed. The robustness is achieved, and continuous control is realized by employing the proposed observer without the chattering problem and the steady-state error. The effectiveness of the proposed observer is confirmed by the comparative experimental results.
