Speed Control of Shunt-Wound DC Motors Using Switching Technique

Document Type


Publication Date



In this paper, a switching feedback control system for speed control of a shunt-wound DC motor is described. In the control system a fast-acting switch periodically opens and closes between the motor terminal and the motor driver in order to estimate the motor’s speed. Theoretical results predicted the stability of the control system and it was shown that the tracking error in the motor’s speed is linearly dependent on the switching rate. To prove the applicability of this approach, an experimental setup was built and the switching control system was implemented using the real-time hardware within MATLAB/SIMULINK™ software.
