This document presents a solution to control an AC induction motor using the
TMS320C24x. This new family of DSP controllers enables cost-effective design of
intelligent controllers for brushless motors which can yield enhanced operation,
fewer system components, lower system cost and increased efficiency. This method
presented is the Field Orientated Control (F.O.C.). The algorithm maintains
efficiency in a wide range of speeds and takes into consideration torque changes
with transient phases by processing a dynamic model of the motor. Among the
solutions proposed are ways to suppress phase current sensors and use an
observer for speed sensorless control.
