Reduction of mechanical vibration of an induction motor with pulsating torque load by feedforward control utilizing an acceleration sensor and a timing sensor

Proposes a method to reduce the mechanical vibration of the V/F controlled induction motor with a pulsating torque load by open-loop feedforward control utilizing a timing sensor. The compensation data for the feedforward control is acquired by the repetitive control using an acceleration sensor. In this paper, the algorithm of the proposed method is presented. The proposed method is applied to a mechanical model system and effectiveness of the method is confirmed by experiments
