ROTARY ELECTRIC MACHINE CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress fluctuations in input/output electric power of a power storage device when torque fluctuations occur to at least one of a plurality of rotary electric machines in a rotary electric machine control system.

SOLUTION: A rotary electric machine control system 10 is configured to include: a rotary electric machine 12 for driving (MG2) 12; a rotary electric machine for power generation (MG1) 14; a power supply part 16 which is common to the MG1 and the MG2; a control block 18 for the MG2; a control block 19 for the MG1; an MG2 control device 60; and an MG1 control device 62. The MG1 control device 62 is configured to include: a fluctuation suppression torque phase calculation part 70 which calculates a torque phase of a fluctuation suppression torque for suppressing torque fluctuation in the MG2; a fluctuation suppression torque amplitude calculation part 72 which calculates a torque amplitude of the fluctuation suppression torque; and a fluctuation suppression torque instruction calculation part 74 which superposes the calculated fluctuation suppression torque to a torque instruction value of the MG1 and calculates the superposed value as a fluctuation suppression torque instruction value.
