SENSERLESS CONTROL APPARATUS FOR SYNCHRONOUS RELUCTANCE MOTOR

摘要

The present invention relates to a sensorless control apparatus of a synchronous reluctance motor , the injection signal generator , the magnetic flux using the current command value and not the injection , by running an electric current from each of the control at start-up , and one to drive the motor stably . In the sensorless control apparatus of a synchronous reluctance motor of this invention is for this purpose , compares the reference velocity and estimated velocity and the current instruction value generating means for generating a current command value based on the comparison result ; On the current command value , the set current of each group by a predetermined operation generates the d, q -axis current command value , and injecting the d power storage ryusinho for the position estimate to the current instruction value d to be the power storage comprises a signal generating means for outputting injection .
