초록

In this. paper, a new technique to estimate both the instantaneous speed and disturbance load torque using a low precision shaft encoder in very low speed range is proposed. To detect the instantaneous speed and disturbance load torque, the Kalman filter which is an optimal full order estimator is used. Experimental results conform the validity of the proposed estimation technique. The effects of parameter variations are discussed, and it is verified that the system is robust to the modeling error.
