ROTATING ELECTRIC MACHINE CONTROL DEVICE

摘要

A rotating electric machine control device comprises a power converter (2) for driving a rotating electric machine (1), a DC voltage detection means (5) for detecting a DC voltage applied to the power converter (2), and a control unit (3) for controlling the operation of the power converter (2). The control unit (3) includes a terminal voltage fixing means (10) that calculates the terminal voltage of the rotating electric machine (1) on the basis of the DC voltage detected by the DC voltage detection means (5) and d-axis and q-axis voltage commands from a voltage command calculation means (9) and performs control for outputting a d-axis current correction value for correcting a d-axis current command so that the calculated terminal voltage matches a terminal voltage command that is a preset control target value, thereby maintaining the terminal voltage to be constant.
