Microcontroller based AC motor speed control

Abstract

The thesis describes the AC motor speed control and the implementation of motor control using ATMEGA8L microcontroller. The industrial and home application is growing complicated and use classical method in speed control can be complexity and costly. For that during the last few years AC speed control by microprocessor is increased significantly. The Atmel AVR microcontroller is excellent for motor control application due to the some futures. The research in first chapter explained the ac motor types and theory in brief and methods of speed control in details. In chapter two design of ac motor speed controls using V/F method and explain effect of increasing and decreasing V/F operation. in chapter three and four design of hard ware and soft ware using c language, complied that by IAR work bench and AVR studio tool ,and implemented special circuit for that .last Chapter experimental result, conclusion and recommendation.
