METHOD TO CONTROL INDUCTION PROPULSION ENGINE Russian patent published in 2012 - IPC H02P23/08 H02P27/06 H02P27/08 

FIELD: electricity.

SUBSTANCE: in the method to control an induction propulsion engine, using the difference between the preset and measured values of active power, the angle of optimal sliding and angle of rotor rotation calculated in accordance with the invention formula, the induction engine stator field rotation angle is determined, by summation of the optimal sliding angle and the rotor rotation angle, using the calculated values of the voltage vector amplitude and the angle of the induction engine stator field rotation, according to the vector PDM law, signals are generated to control an autonomous voltage inverter, and in the mode of induction engine field weakening, using the difference between maximum specified and calculated values of the voltage vector amplitude, additional sliding is generated, with account of which a new value is produced for the angle of the stator field rotation, and signals are generated to control an autonomous voltage inverter, at which sliding and current of the induction engine increase, and the mode of power constancy is preserved as the field weakens.

EFFECT: control of an induction propulsion engine in a wide range of rotation frequency under conditions of power limitations of an incoming source of power in a vehicle.
