Abstract
The employment of power electronic devices in the control techniques of electrical drives is becoming more common in current technology. A DC motor's speed can be adjusted by adjusting the field flux, armature resistance, or the terminal voltage provided to the armature circuit. Field resistance control, armature voltage control, and armature resistance control are the three most popular speed control methods. However, in this case, a drive approach has been employed for DC motor speed control, which is a chopper and some power electronics components. It has been demonstrated here how to employ chopper and power electronics devices to manage the torque and speed characteristics of a DC motor. The model is now simulated and analysed in MATLAB (Simulink) under changing speed and torque conditions.
