A Control Method of a Regenerative Power Storage System for Electric Machinery

This paper presents a novel state-averaged model and an effective control method of a regenerative power storage system for electric machinery to save the energy. A vector control method is employed in order to control a torque instantaneously in the case of acceleration and regeneration of the motor. The regenerative power is stored and then provided to a motor by the regenerative power storage system that consists of an electrolytic capacitor and a bi-directional DC-DC converter. We have designed a new control system using both a feedback and a feed-forward path to achieve the stability and the quick response. The effectiveness of the proposed control method is illustrated by both a simulation and an experiment
