Abstract: This paper presents sensorless speed control of a brushed DC motor minimizing the system cost without any modification on the motor side. It uses natural tracking control algorithm that is robust to systems with unmodeled dynamics and external disturbances. Control algorithm was verified by physical experiments.

Keywords: motor speed, control, sensorless, natural tracking, robust.
