FPGA Implementation of PWM Control Technique for Three Phase Induction Motor Drive

The primary function of any adjustable speed motor drive is to control the speed, torque, acceleration, deceleration and direction of rotation of machine. Unlike constant speed systems, the adjustable drive permits the selection of infinite number of speeds within its operating range. Most multipurpose production machines benefit from adjustable speed control, since frequently their speed must change to optimize the machine process or adapt it to various tasks for improved product quality, production speed or safety. The control circuit in FPGA clearly has an advantage of reconfiguration over the other methods.
