Speed control of DC motor using PWM technique
DC motors are widely used in industrial applications. In this regard controling the speed in wide range is another aspects. For this purpose, here is an abstract of the project
Electrical is the most valuable and precious one for this universe. In this
the motor plays an important role. Hence we want to control the motor for our requirements.
The aim of this project is to control the speed of the DC motor. Generally, DC motors are applicable for effective speed control and high starting torque applications like traction, lift, etc.
Basically DC motor speed control is done by voltage control, armature resistance control and flux control methods. But in this project we are control the speed of the DC motor by Pulse Width Modulation (PWM) technique. From this method we can obtain a smooth speed variation with out reducing the starting torque of the motor.
PWM technique also eliminate harmonics. Matlab tools are availabe for DC machine. By using this, a matlab using simulink of the speed control of motor can be done in a matlab environment and also can be verified by experiments.
