Abstract: This paper deals with speed control of separately excited DC motor control in a high performance manner. There are four different parts of control of DC motors used in this project . Using chopper as a converter the speed of DC motor is controllable. The chopper firing circuit gets signal from controller and then by supplying variable voltage to the armature of the motor the desired speed chopper is achieved. There are two different types of control loops, current controller and speed controller. The controller used is Proportional-Integral type. Using this controller the delay is removed and fast control is achieved. Separately excited DC motor is designed . The current and speed controller is designed and in order to get stable and high speed control of DC motor. The simulation of model is done and analyzed in MATLAB (Simulink) under varying speed and torque condition.
Keywords: chopper circuit, DC motors, open and closed loops, MATLAB (SIMULINK).
