DC motor widely used-high precision digital controls. Speed control of dc motor is achieved with smooth starter by using buck converter. Hard switching causes unsatisfactory dynamic behavior produces abrupt variations in the V & I of the motor overcome by dc-dc buck power converter by PID controller. A separately excited dc motor is used for this simulation. The PI control method is used in which the settling time is reduced. The proposed system with PID control is used as outer voltage control loop. Dc-dc buck converter is mainly used for regulate the desired output voltage level and maintain DC motor speed as constant. Any change in torque does not affect the speed of the motor. Step less velocity and smoothness in armature voltage control with PWM technique is used.
