Elimination of position-dependent disturbances in constant-speed-rotation control systems

Abstract This paper describes a new approach to eliminating position-dependent disturbances in constant-speed-rotation control systems. Focusing on the fact that this kind of disturbance constitutes a periodic function of the rotational angle, a new concept called the “position domain” is introduced, and the design of the proposed control system is carried out in the position domain instead of the time domain, so as to eliminate such disturbances completely, regardless of any changes in the rotational speed.
