Micro-controller is a very widely used electronic component and today we are showing your another example of it. Today's' project topic is "DC motor speed control using Microcontroller PIC16F877A" and we are sharing full project report of it. This is a very good project work for final year Electronics and Electrical students. This project is mainly focus on DC motor speed control system by using microcontroller PIC 16F877A. It is a closed-loop real time control system, where optical encoder (built during this project) is coupled to the motor shaft to produce the feedback speed signal to controller.
Pulse Width Modulation (PWM) technique is employed where its signal is generated in microcontroller. Micro-controller acts as proportional (P) controller with Kp =1 in this study. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.
The PWM signal are going to be send to motor driver to vary the voltage provide to motor to take care of at constant speed. A program in Visual Basic 6 is developed to produce a graphic computer program (GUI) for the user to enter desired speed at laptop. Besides, it additionally shows a graph of motor speed versus time to let the user monitor the performance of the system simply. supported the result, the reading of optical encoder engineered is sort of reliable. Through the project, it may be ended that microcontroller PIC 16F877A will management motor speed at desired speed though there's a variation of load.
The goal of this project is to design a DC motor speed control system by using microcontroller PIC16F877A. It is a closed-loop real time control system. The controller will maintain the speed at desired speed when there is a variation of load. By varying the PWM signal from microcontroller (P controller) to the motor driver, motor speed can be controlled back to desired value easily.
