This paper describes a MATLAB/Simulink realization of the DC motor speed control method by controlling the voltage applied to the armature circuit using a pulse width modulated (PWM) chopper drive. Torque-speed characteristics are obtained for different values of switching frequency to demonstrate its effect on the linearity of the characteristic. The proposed simulation model is developed as a part of a software laboratory to support and enhance undergraduate electric machinery courses at Nigde University, Nigde, Turkey.
