METHOD FOR CONTROL OF SWITCHED RELUCTANCE MOTOR Russian patent published in 2020 - IPC H02P25/08 H02P25/86 H02P25/89 H02P25/92 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in electric drives of various mechanisms. In control method of switched reluctance motor, which includes during each control cycle measurement of supply voltage, correction of sampling frequency of phase currents depending on measured value of supply voltage, inclusion of next phase depending on previously determined time, measurement of current in it, setting of current in it, accumulation of discrete in time sampling current of this phase with its increase at measuring interval, generation in this phase of current depending on its specified and measured values by relay law, disconnection of said phase depending on previously determined time, sampling of current of next connected phase is successively grouped with current sampling of previous connected phase, then harmonic composition of grouped sample is determined, then, normalized mismatch of stator and rotor teeth position is determined at phase connection moment, then normalized mismatch is corrected, then moment is determined for subsequent switching of next phase and moment of time for disconnection of this phase, wherein the time point for phase connection is determined such that it corresponds to the mismatched position of the stator and rotor teeth for that phase, the time point for phase disconnection is determined such that it is anticipated with respect to the phase transition into the generator mode, and the relationship between the harmonic composition of the grouped current samples of the next connected phase and the previous connected phase and the standardized mismatch of the position of the stator and the rotor teeth of the switched reluctance motor is set in advance.

EFFECT: improved control quality of switched reluctance motor.
