METHOD FOR CONTROL OF AC ELECTRONIC MOTOR AND TRACKING SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC H02P6/16 H02P27/04 G05B11/01 

FIELD: electricity.

SUBSTANCE: in the method for control of an AC electronic motor three-phase power-supply voltage is generated of the sign of difference between the signal of the three-phase sensor of the synchronous motor rotor position and the signal of the synchronous motor current three-phase sensor. The control signal is generated by way of subtracting the speed feedback signal and the angle feedback signal from the from the angle assignment signal. The tracking system with an AC electronic motor comprises a modulator, a three-phase sensor of the synchronous motor rotor position, a three-phase demodulator, a three-phase summator, a three-phase relay, a three-phase converter, a three-phase synchronous motor current sensor, a three-phase synchronous motor; additionally introduced are a reducer with an angle sensor and the synchronous motor speed sensor, a summator with one summation input and two countdown inputs output connected to the tracking system elements as per the invention formula.

EFFECT: provision of characteristics identical to those of a DC collector motor by means of analytical design of the AC electronic motor shaft turn controller, optimal in terms of accuracy.
