MOTOR MUTUAL DRIVING-BASED ROTATION SPEED AND TORQUE CONTROL METHOD, AND RELATED APPARATUS

WIPO Patent Application WO/2024/082382

A1

Provided are a motor mutual driving-based rotation speed and torque control method and apparatus. The rotation speed and torque control method comprises: for a traction motor (M1) and a load motor (M2) which are in coupled mutual driving, controlling the rotation speed of the load motor (M2) according to a rotation speed limit value of the load motor (M2) (201); according to the rotation speed limit value of the load motor (M2), a rotational inertia value of a train, a resistance moment value of the train, a first corresponding relationship between the rotation speed and the angular speed of the load motor (M2), a second corresponding relationship between the angular speed and the acceleration of the angular speed, and a third corresponding relationship between the resistance moment of the train, the rotational inertia value of the train, the acceleration and the torque of the traction motor (M1), performing calculation to obtain a torque limit value of the traction motor (M1) (202); and, according to the torque limit value of the traction motor (M1), controlling the torque of the traction motor (M1) (203). The torque of the traction motor (M1) does not affect the rotation speed of the load motor (M2), thus achieving rotation speed and torque decoupling of the traction motor (M1) and the load motor (M2) in coupled mutual driving to a certain extent.
