ONLINE PARAMETER CORRECTING METHOD FOR SENSORLESS CONTROL OF AN INTERIOR PERMANENT MAGNET SYNCHRONOUS MOTOR CAPABLE OF IMPROVING SENSORLESS CONTROL PERFORMANCE
ONLINE PARAMETER CORRECTING METHOD FOR SENSORLESS CONTROL OF AN INTERIOR PERMANENT MAGNET SYNCHRONOUS MOTOR CAPABLE OF IMPROVING SENSORLESS CONTROL PERFORMANCE
PURPOSE: An online parameter correcting method for sensorless control of an interior permanent magnet synchronous motor(IPMSM) is provided to remove errors in counter electromotive force estimation.;CONSTITUTION: A speed estimator(140) generates an estimation speed and an estimation angle using an error value from an observer(130). A speed controller(150) controls the speed of an IPMSM(100) based on the estimation speed and the estimation angle. A current controller(160) controls a current to operate the IPMSM at the estimation speed. A three-phase voltage is applied to a PWM inverter(180). The PWM inverter controls the IPSMS.;COPYRIGHT KIPO 2013
