Abstract
Speed variation in a pump, a compressor or a wheel of electric vehicle often causes vibration and noise, which shorten the life of the machine. Although the repetitive control can suppress the speed variation, there are the following problems : ・If a reference velocity changes, the period of the speed variation changes and the effect of the suppression becomes bad. ・The tuning parameters are difficult to be tuned. In this paper, we propose a controller composed with PI controller and the controller suppressing the specified frequency waves based on the internal model principle. It is verified by simulations and experiments that the proposed method overcomes the above mentioned problems.
