Title:
AC ROTATING ELECTRIC MACHINE CONTROL DEVICE AND ELECTRIC POWER STEERING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/143120
Kind Code:
A1
Abstract:
An AC rotating electric machine control device is provided with an AC rotating electric machine having x-phase windings (where, x is 3 or more), an angle detector, a current detector, a voltage command calculator, and a power converter. The current detector can detect the current of at least one phase of the x-phases at a present current detection timing and, when it is impossible to detect the currents of at most (x-1) phases, estimates by calculation the currents of the (x-1) phases, which have been impossible to be detected at the present current detection timing, on the basis of the x-phase detection currents obtained at a past current detection timing, the one phase detection current that has been able to be detected at the present current detection timing, and the amount of angle change from the past current detection timing to the present current detection timing.
