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
