Abstract
An electrical drive consists of a motor powered by electricity, a power, with an energy-transmitting shaft. In modern electrically driven systems, power electronics converters serve as power controllers. The two main types of electric drives are AC drives and DC actuators. This study presents highly effective design and modeling techniques for individually stimulated DC motor speed control. To create a controller that regulates speed for a Separately Excited DC (SEDC) motor, a converter called a chopper circuit can be used. The controller sends a signal to the chopper discharge circuit, which then adjusts the voltage sent to the motor's armature to drive the chopper at the desired speed. The current controller and speed controller are two different types of control loops. A proportional-integral controller is used. Fast control has been rendered possible with this controller by doing away with the delay. A DC motor that is independently excited is made, and a current & speed regulator is constructed to enable a steady state plus high-speed control of the DC motor. The model is analyzed and tested in MATLAB (Simulink) under various speed and torque situations. Satisfactory outcomes are obtained, demonstrating the chopper approach's ability to regulate the rotation speed generated by an SEDC motor.
