Abstract
A device and a method control a motor using a maximum torque per ampere field module and a direct flux vector control module. The method: determines by the direct flux vector control module reference voltages in a fτ framework; drives the motor with the summed voltages; measures a motor current vector; determines a high frequency injection voltage so that the high frequency current response of the motor to the high frequency injection voltages is perpendicular to the measured motor current vector; determines an estimated flux from the measured motor currents and the voltage references; and determines, from the estimated flux and the high frequency sinewave signal, the reference flux so that the high frequency flux response to the injected voltage is aligned with the measured current vector.
