CONTROL METHOD AND SYSTEM FOR MOTOR DRIVING AND CONTROL METHOD FOR AIR COMPRESSER IN FUEL CELL SYSTEM USING THE SAME

摘要

A motor drive control method and system capable of remarkably improving the efficiency of a motor through reduction of switching loss and current ripple loss of an inverter in a low-speed drive period of a high-speed motor. The motor drive control method includes driving a motor torque based on the speed command value and controlling a speed of the motor based on a predetermined period and a duty ratio based on the speed command value, And repeatedly turning on / off the torque of the motor.
