Abstract
A system and method for controlling an alternating current (AC) motor using a Field Programmable Gate Array (FPGA) to read the current and position measurements in an the AC motor, perform digital filtering of the position and current data, provide very precise synchronization of the measured phase current and position data, and output the data to a phase converter for control of the AC motor.
