Abstract

Nowadays, Microchip PIC has become one of the popular tools in the area of controller especially in robotics and motor control. The main objective of this project is to control the speed oflow power DC motor by varying the duty ratio of Pulse Width Modulation (PWM) waveform, produced by PIC16F877A microcontroller. In addition, observation of the DC motor performance has been made by investigating the relationship between PWM frequency and the DC motor performances. MIKRO C software is used to write and verify the PIC source code inC language. Finally, the simulation of the controller circuit and the PIC programming has been performed by using PROTEUS 6 LIFE software. The results show that the speed of the DC motor is proportional to the PWM duty ratio. The speed of the DC motor will increase if the duty ratio is increase within a certain limit. Further more, the, voltage spike at the DC motor input terminal can be decrease by increasing the frequency of PWM pulse.·
