Abstract

This paper proposes position-sensorless disturbance observer (PSDOB) for DC brushed motor (abbreviated as DC motor later). The aim of this method is to suppress disturbance for position-sensorless motion control of DC motor. At first, block diagram of motor system is transformed and disturbance torque is defined as modeling errors between real motor model and nominal model. Next, disturbance torque is estimated from current reference, voltage reference, and measured current. Finally, estimated disturbance torque is fed back to suppress the disturbance torque. Therefore, robust acceleration control can be realized by utilizing PSDOB. The utility of the proposed method is experimentally verified.
