Modeling, Design and Control of Speed DC motor using chopper

Abstract

An electric motor, a power controller, and an energy-transmitting shaft make up an electrical drive. Power electronics converters are utilized as power controllers in contemporary electrically driven systems. DC actuators and AC drives are the two primary categories of electric drives. This study presents design and modeling techniques for very effective individually stimulated DC motor speed control. A DC motor speed controller can be implemented using a chopper circuit as a converter. The controller transmits a signal into the chopper firing circuit, which in turn generates the desired speed of the chopper by varying the voltage supplied to the motor's armature.One type of controlling loop is the speed controller, and another is the current controller. A proportional-integral controller is used. Eliminating the delay with the aid of this controller makes rapid control possible. It creates a separately stimulated DC motor. A current and speed regulator are built in to give the DC motor high-speed control in a steady condition. Under different speed and torque conditions, the model is simulated and examined in MATLAB (Simulink). Results that are satisfactory are achieved, validating the capacity of the chopper approach to control the speed of a DC motor.
