MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD

Title:

MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2014/132766

Kind Code:

A1

Abstract:

A motor control device is provided with: a current command value calculation means which, on the basis of a torque command value inputted from outside and the rotation speed of a motor, calculates a basic current command value; a first compensation means which compensates for a delay in the rotor magnetic flux response of the motor (3) by amplifying the basic current command value; a first current command value limiting means for limiting a post-compensation current command value by a first current limiting value; a second compensation means which, on the basis of a current amplification command value calculated by the first compensation means and a first post-limitation current command value calculated by the first current value limiting means, calculates a compensation value for the current amplification command value; an addition means which calculates the post-compensation current command value by adding the current amplification command value and the compensation value; and a motor control means which, on the basis of the first post-limitation current command value, controls the motor (3), the second compensation means calculating, as the compensation value, a command value corresponding to a portion limited by the first current limiting value of the current amplification command value.
