Abstract
In this paper, a voltage disturbance observer (VDOB) and counter electromotive force estimation observer (CFOB) are proposed. A voltage disturbance is defined as the electrical disturbance of DC brushed motors. A VDOB estimates a voltage disturbance from a voltage reference and the measured current. Utilizing a VDOB, high-performance motion control is realized. A CFOB estimates the counter electromotive force from an estimated voltage disturbance. By estimating the angular velocity from the counter electromotive force, position-sensorless motion control is realized. Therefore, high-performance position-sensorless motion control of DC motors is realized by combining these observers. The validity is experimentally verified.
