Title:
MOTOR CONTROL DEVICE, AND CONTROL METHOD OF ELECTRIC VEHICLE MOTOR
Document Type and Number:
Japanese Patent JP2002252902
Kind Code:
A
Abstract:
To suppress a continuous vibration phenomenon of an electric system generated during regenerative control.
A vibration suppression control part confirms whether an operating point exists in a maximum torque region, or in a throttling region, based on a q-axis current command value Isq* and a filter capacitor voltage Vf. When it is decided that the point is in the throttling region, only a steady value is changed while the ratio in throttling the q-axis current command value Isq* in the throttling region is unchanged. Moreover, the direction for the change is a direction to make the q-axis current command value Isq* to be reduced (to be directed to '0').
