Abstract

Recently, motor applications not only use the maximum speed. It maybe uses only 5% of its speed. So, the speed of the motor must be control. For some applications, motor is using not only one direction but with alternate direction to control a machine. In industrial field, DC motor acting an important part in industrial. Besides, in modern era the manual controller is also not practical which can waste cost and time. According to this situation it is important to make a controller to control the speed of DC motor which user can monitor their system at certain place rather than going to the plant. Therefore, the aim of this project is to control direction either forward or backward of DC motor by using microcontroller and to study speed control of DC motor using PWM technique. It is operated by four quadrant H-Bridge DC motor controller using PIC18F4550.Four Quadrant Circuit is used in this circuit. It is create by using simulation software known as Proteus software. The simulation is also done for testing the four quadrant and also the control circuit. Four MOSFETS are used in the four quadrant circuit. Two of them are TIP 41C and TIP 42C. The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement as they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions. The motor is controlled by using PWM which is pulse with modulation. It is observed that the voltage increases as the PWM increases. The maximum of the PWM is 255 whereas the maximum voltage is 5.101V. The LCD is also used in this project to show the maximum and minimum of the PWM. Overall, with this project, it can control not just the PWM, but the speed of the motor.
