Closed Loop Speed Control of DC Motor using Digital Controller

DC Motors are widely used in industries especially in areas where wide range of speed is required. So DC Motors are used in many adjustable speed drives. So the main aim of this project was to control the speed of a DC Motor using PI Controller whenever there are fluctuation in the input. In this course I learnt the architecture of AtMega328P microcontroller its pin configurations and the AVR libraries. I was able to work with the ADC libraries of the microcontroller. Then I learnt the concept of PWM dead time generation hardware interrupt and quadrature pulse counting. I learnt the hardware connections for these concepts. I understood the basics of digital controller. I learnt how to implement the digital controller in AtMega328P. I also learnt the code required for implementing these using the AVR libraries.At last using all these concepts I learnt to implement the closed loop RPM control of the DC motor.
