The Torque-current Observer Design for Speed.Torque Control of DC Motor

직류 전동기 속도.토크 제어에 대한 토크전류 관측기 설계

In this paper, the load torque observer is designed for speed and torque control of DC motor. Load torque is very sensitive to the variation and disturbance of the input parameters. The proposed system can accurately estimate the instantaneous speed even at the low speed range by using the load torque observer based on the torque component of DC motor. The system becomes robust against disturbances using a feed-forward control of the load torque estimated automatically at the speed observer.
