Abstract

PURPOSE:To smooth the change-over of control for a high-speed region and a low- speed region of an induction motor by providing a means adjusting the device constant of an operator so that the phase difference between magnetic fluxes calculated by a current model and a voltage model may become zero. CONSTITUTION:In the transvector control device for an induction motor, a means is provided to detect the phase difference between the phase phii of the magnetic flux calculated by a magnetic flux operator by a current model and the phase phiv of the magnetic flux calculated by a magnetic flux operator by a voltage model and adjust the device constant of the operator by the current model so that the phase difference may become zero. For example, when the rotating speed of a motor increases to change from the current model to the voltage model, the above phase difference theta is detected by a phase difference detector 1 to feed the phase difference theta to a calculating controller 4 directly or through a polarity inverter 2 and a calculating-control output making the phase difference theta zero is sent to a terminal 40.
