碩士 === 大葉大學 === 自動化工程研究所 === 90 === This paper presents a novel electrical hardware for the speed control of the regenerative braking system. First, we develop a charging and discharging system to operate between a battery and a motor. When the battery on the charging mode, the motor obtains energy and speeds up. Then the battery on the discharging mode, the motor changes as a generator, which can turn the dynamic energy of the motor to electric energy. This electric energy is discharged to the battery. And thus make the motor speed down. Through modulating the ratio of the time between the charge and discharge of battery, we can perfectly control the speed of the motor. Moreover, as a result of the energy discharge of the motor, the battery can conserve the energy consuming. Additionally, we design two of PI and fuzzy controllers for the speed control of the motor, and compare with their performance. The results of experiment show that the fuzzy controller has a larger operating range and better performance than the PI controller.
