Document Type and Number:
Japanese Patent JP6424790
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor control device exerting a damping effect.SOLUTION: A damping feedback processing section 31 of a motor control device 30 for controlling a motor which performs driving for travel of a vehicle, comprises a bandpass filter 32, a conversion part 33, a damping torque operation part 34, an upper and lower limit guard processing part 35, and an upper and lower limit guard change part 36. The upper and lower limit guard change part 36, based on a change rate of a torque command value pertaining to drive of the motor, changes an upper limit value and a lower limit value of the upper and lower limit guard processing part 35. The upper and lower limit guard processing part 35 carries out upper and lower limit guard processing using the changed upper limit value and lower limit value.EFFECT: The upper limit value and the lower limit value can be changed, and therefore, when resonance is large, a damping effect for cancelling the resonance can be exerted. Further, the torque command value becomes not excessively corrected, and deterioration of the motor control can be prevented. Accordingly, both the damping effect and stability of the motor control can be achieved.SELECTED DRAWING: Figure 2
