CONTROL DEVICE FOR ROTARY ELECTRIC MACHINE
This abstract first appeared for US patent application 20250070695 titled 'CONTROL DEVICE FOR ROTARY ELECTRIC MACHINE
Original Abstract Submitted
a control device is applied to a system including a rotary electric machine having a stator having a stator winding and a rotor having a field winding. the control device includes an operation unit that operates a current flowing through the stator winding and a field current flowing through the field winding in order to control a torque of the rotary electric machine to a command torque, and a determination unit that determines whether the command torque increases suddenly. the operation unit increases a degree of excitation of the field winding during a predetermined period from when it is determined that the command torque suddenly increase until the torque of the rotary electric machine converges to the command torque, compared to the degree of excitation of the field winding during a period after the predetermined period.
