A device for a 'according to the field orientation principle of' operating, universal control device of an induction motor

摘要

A torque feedback system is employed in a universal field- oriented (UFO) controller to tune a torque-producing current command and a slip frequency command in order to achieve robust torque control of an induction machine even in the event of current regulator errors and during transitions between pulse width modulated (PWM) and square wave modes of operation.
