Machines have served the humanity starting from a simple ceiling fan to higher industrial applications such as lathe drives and conveyor belts. This research work aims at providing an appropriate software based control system because it provides computer featured applications, prevents rapid signal loss, reduces noise while also significantly improves the steady state and dynamic response of the motor. In this research paper, we have worked on DC motors due to its significant advantages over other types of machine drives. In industry DC motor is widely uses for speed control and load characteristics, it's easy controllability provide effective and precise output so application of DC motor is large for commercial purpose. Speed control of DC motor is very crucial in application where required speed is precision and correcting signal representing and to operate motor at constant speed, so we used PWM method which are fulfill all requirements to speed control of DC motor. PWM based speed control system consists of electronic components (integrated circuits, Sensors etc.). In this paper, to control the speed of DC motor using Pulse Width Modulation (PWM) method. Microcontroller is used to generate PWM. MATLAB is used to drive the motor . Rectifier circuit is used for power supply to circuit and motor. This paper shows that precise and accurate control of small DC motors can be done efficiently without using costly components and complicated circuit.
