초록
A control approch for the robust position control of IM based on the binary disturbance observer is described. The conventional binary observer is used to remove the chattering problem of variable structure system. However the steady state error may be existed, because the conventioal binary observer etimates external disturbance with constant boundary layers. Thus in order to overcome this problem, the improved binary observer is proposed. By employing the proposed observer, the robustness is achived and the continuous control is realized without the chattering problem and the steady state error. The effectiveness of the proposed observer is confirmed by the computer simulation.
