METHOD FOR DETERMINING ANGLE OF ROTATION OF ROTOR OF PERMANENT MAGNET SYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2021 - IPC H02P21/18 H02P21/24 H02P6/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in systems of vector control of a synchronous electric motor with permanent magnets without the use of sensors for measuring the angle of rotation of the rotor of the motor.

EFFECT: invention increases the speed of sensorless determination of the angle of rotation of the rotor. The sensorless method for determining the angle of rotation of the rotor consists in measuring the instantaneous values of the currents and voltages on the stator phases. Then the measured values are transformed into a stationary coordinate system αβ. Determination of the rotor position is based on estimates of the flux linkage components obtained using an adaptive observer based on the dynamic expansion and mixing of the regressor, which is characterized by increased speed.
