Abstract: Variable speed induction motors are one of the most researched topics in the industry today. As the digital control of the motors took over the analog control, the search for an efficient speed control scheme for ac induction motors has started. Along with the speed control mechanism the selection of the controller is also of utmost importance. As there are different controllers available like microcontroller, FPGA, dsp, Choosing the most efficient controller for the given application is crucial. This project is a comparison study of speed control of induction motor using a microcontroller and FPGA. The induction motor is driven using both FPGA and microcontroller and the results are studied. The system is tested and experimental results are recorded for various speed for both controllers.

Keywords: Induction Motor; Microcontroller; Pulse Width Modulation Inverter; Speed Control; FPGA.
