<P>PROBLEM TO BE SOLVED: To provide a motor control device correcting a mutual interference component between a d-axis and a q-axis to control a motor, and being capable of suppressing current pulsation and convergence delay generated when a control state of the motor is changed. <P>SOLUTION: A motor control device 1 has a correction value generation part 104 and a filter part 105. The correction value generation part 104 generates a d-axis correction value and a q-axis correction value for correcting a mutual interference component between a d-axis and a q-axis on the basis of a d-axis current command Id*, a q-axis current command Iq*, and an angular velocity ω. The filter part 105 makes a specific frequency component among frequency components included in the d-axis correction value and the q-axis correction value pass through. Further, characteristics of the filter part 105 are changed depending on a control state of a vehicle driving motor M1. Thereby, a high-frequency component generated when the control state of the vehicle driving motor M1 is changed can be removed appropriately. Therefore, current pulsation and convergence delay generated when the control state of the vehicle driving motor M1 is changed can be suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
