1. A rotating electric machine control device for controlling a drive of a rotating electric machine having a plurality of winding sets which are magnetically coupled with each other, the rotating electric machine control device comprising:
an inverter arranged in each of the winding sets and having a high potential-side switching element corresponding to each phase of a respective winding set, and a low potential-side switching element connected to a low potential side of the high potential-side switching element; and a controller controlling the inverter in each of the winding sets, wherein: each of the winding sets and the inverter corresponding to a respective winding set provide a system; the controller has:
a signal generator generating a control signal for controlling on and off operations of each of the high potential-side switching elements and the low potential-side switching elements;a disturbance voltage estimating device calculating a disturbance voltage estimation value that is obtained by estimating a disturbance voltage, which is generated in a normal system where a short circuit failure does not occur, by a current flowing in a failure system when the short circuit failure occurs in the failure system; anda command calculating device calculating a normal system command value, related to a control of energization to the normal system, in accordance with the disturbance voltage estimation value; an upper-side bus connects high potential sides of high potential-side switching elements in each of the winding sets; a lower-side bus connects low potential sides of low potential-side switching elements in each of the winding sets; and the short circuit failure is defined as a failure, in which the upper-side bus or the lower-side bus is electrically connected to one phase of a respective winding set. |
