Abstract:
1. A motor-generator control system for controlling a motor-generator, the motor-generator having a first set of multiphase windings and a second set of multiphase windings, the first and second sets of multiphase windings being arranged to be spatially shifted in phase from each other, the motor-generator control system comprising: an allocating unit configured to, upon input of workload request for the motor-generator, determine: a first torque to be allocated to the first set of multiphase windings, a second torque to be allocated to the second set of multiphase windings, a resultant torque of the first torque and second torque meeting the input workload request for the motor-generator, and a phase difference based on the first torque and second torque to be respectively allocated to the first and second sets of multiphase windings, the phase difference representing a phase difference between a first alternating current for each phase winding of the first set and a second alternating current for a corresponding one phase winding of the second set, the input workload request and the phase difference determining the first alternating current for each phase winding of the first set and the second alternating current for each phase winding of the second set; and an energizing unit configured to energize, based on the phase difference, the first set of multiphase windings and the second set of multiphase windings to create the first torque and the second torque, respectively.
