In a modern technology the use of power electronic devices in the control strategies of electrical drives is increasing. The speed of a DC motor can be varied by controlling the field flux, the armature resistance or the terminal voltage applied to the armature circuit. The three most common speed control methods are field resistance control, armature voltage control, and armature resistance control. But here a technique of drive has been used for DC motor's speed control is chopper and some power electronics devices. It has been shown here the use of chopper and power electronics devices which paves the way of controlling also torque and speed characteristics of DC motor. Now the simulation of model is done and analysed in MATLAB (Simulink) under varying speed and torque conditio
