DOUBLE FIELD ORIENTATED VECTOR CONTROL STRUCTURE FOR CAGE INDUCTION MOTOR DRIVE

Abstract

There is proposed a new structure of vector
control for the short-circuited induction motor drives fed
by voltage-source inverter (VSI) with voltage-feedforward
pulse-width modulation (PWM), which combines the
advantages of two types of field-orientated procedure, i.e.
rotor-field orientation and control for generating statorcurrent
control variables by controllers and stator-field
orientation, for computation of the stator-voltage ones.
