FIELD: machine building.
SUBSTANCE: invention relates to control over traction system and power transmission with synchronous motor. Control system comprises a measurement unit, a controller and a position sensor. Controller receives the command of the target torque supplied to the traction and power transmission system, and calculates target values of excitation current and torque generating current. Torque control unit is used to generate control value of torque generating current in accordance with target value of torque-generating current and operating value of torque-generating current, generating the target modulation and frequency factor and, ultimately, outputting the simulated control signal PWM for the synchronous motor with permanent magnets.
EFFECT: high efficiency of the system, stable operation of the system having a lower switching frequency.
