Design and Performance Evaluation of DC Generator Control System for Cortrolling Torque of Rotating Shaft

회전축의 정밀 토그 발생용 직류 발전기 제어장치의 설계 및 성능평가에 관한 연구

A DC generator control system was designed to control the torque of a rotating shaft precisely. The control system is composed of a strain gage type torque cell, a torque cell amplifier, a computer, a D/A converter, a error detector, a DC voltage amplifier and a resistor. The response test under unit step input and the dynamic stability test for the designed control system were carried out. It was confirmed that the settling time from the response test is about 4 s and the error from the dynamic stability test is less than 0.06% of rated output of torque cell. The designed control system may be used to control a DC generator which may be used to apply torque to a rotating shaft.
