Abstract
This thesis is mainly concerned on DC motor speed control system by using microcontroller (ARDUINO DUE-ARM Microcontroller). It is a closed-loop real time control system, where optical encoder / Taco generator are coupled to the motor shaft to provide the feedback speed signal to the Microcontroller (MC) board. In case of using the Taco generator feedback, its output is measured using the internal Analog to Digital Converter (ADC) of the Microcontroller, Pulse Width Modulation (PWM) technique is used where its signal is generated using Microcontroller. Proportional Integral Derivative (PID controller is also implemented digitally using Microcontroller. The PWM signal will send to motor driver circuit to vary the voltage supply to motor to maintain a constant speed. There are two methods for the user to enter desired speed and the desired direction to the Microcontroller either using the Keypad or using a wireless technology. Also the desired speed and the actual measured speed values display in at a Liquid Crystal Display (LCD). Through the thesis, it can be concluded that Microcontroller can control motor speed at desired speed and the PID controller parameters can be varied easily during operation using the data entering method. The reference speed and the actual speed can be monitored using Digital Oscilloscope (D-OSC) through the built-in Digital to Analog Converter (DAC) channels of the Microcontroller. The simulation and experimental results are presented to insure the validity of the used approaches. The given experimental results are considered at 60% of the motor rated power values.
