Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/053412
Kind Code:
A1
Abstract:
In the present invention, an MG-ECU functions as a motor control device that controls a motor generator connected to an engine. Using a revolution speed detection value obtained by detecting the revolution speed of the motor generator, the MG-ECU performs feedback control so as to bring the revolution speed close to a command value, thereby causing the motor generator to output a damping torque in a phase reverse to that of torque variation in the engine. The MG-ECU switches the control gain of the feedback control between a plurality of levels including a low gain and a high gain. Furthermore, regarding a first transition (UT), in which transition is made from the low gain to the high gain, and a second transition (DT), in which a transition is made from the high gain to the low gain, a non-linear gain transition is implemented at least during the second transition (DT).
