Application of DC/DC Buck Power Converter in DC Motor for Speed Controlling Using PI Controller
نویسندگان
چکیده
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 behaviour produces abrupt variations in the V & I of the motor overcome by dc-dc buck power converter by PI controller. A separately excited dc motor is used for this simulation. The proposed system with PI 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.
