PROBLEM TO BE SOLVED: To effectively reduce a possibility that excessive current feedback control is worked to cause generation of unintended overshoot in a current value even in the case where current deviation is large at switching from a rectangular wave voltage phase control mode to an overmodulation current control mode, in a motor drive control system using a plurality of control modes.SOLUTION: In a motor drive control system for switching a control mode among a plurality of control modes to perform drive control of a motor, at switching from a rectangular wave voltage phase control mode to an overmodulation current control mode, in the case where current deviation between a current command and an actual current value is larger than a predetermined threshold, a regulation of a voltage command based on current feedback is restricted. |
