반파정류브러쉬없는 동기모우터의 디지탈제어 = Digital Control of Half-wave Rectified Brushless Synchronous Motor

다국어 초록 (Multilingual Abstract)

Digital control of half-wave rectified brushless synchronous motor is one of the attractive and interesting research subjects in the field of industrial robot. A direct-drive(D-D) system is being developed to control the forces. the position of high speed and the constant speed in high accuracy. The PI control without any additional control process has very poor response and inaccuracy of position and speed. It is one of the important problems to reduce the fluctuation of position and speed. In order to improve those problem, we proposed a repetiteve control with the position memory type and the constant speed by learning process. It provides us the good response of system and the improvement of the position and the speed accuracy.
