摘要

FIELD: electrical engineering. ;SUBSTANCE: invention relates to the field of electrical engineering and can be used in sensorless control systems for a synchronous electric motor with permanent magnets. The method of direct sensorless control of the angular position of the rotor of a synchronous electric motor consists in measuring the instantaneous values of current and voltage at the stator phases. Further, they are transformed into a stationary coordinate system αβ, and the position of the rotor is determined based on the estimates of the flux linkage components. The calculation of signals for controlling the angular position of the rotor is carried out using a robust control law with an extended observer, which makes it possible to compensate for external and parametric disturbances. ;EFFECT: improving quality of position control in the presence of external and parametric disturbances. ;1 cl, 5 dwg
