High precision and good command response are the most important requirements in performance of constant speed rotation control systems. It is the rotational speed fluctuations caused frequent by rotational angle dependent disturbances that have hindered all efforts to improve the precision of such systems.
This paper proposes a new approach focusing on the fact that this kind of disturbance constitutes cyclic function of the rotational angle. The proposed design is set in the ‘angle domain’ instead of the ‘time domain’ so as to eliminate such disturbances completely without regard to the rotational speed.
The results of the simulation reported in this paper will prove that the constant speed rotation control system designed according to the proposed approach removes all rotational speed fluctuations apart from speed setting changes.
