More Information
Summary:To provide a controller for rotary electric machine which can determine an abnormality of a calculation unit which calculates voltage command values on a rotating coordinate system of d-axis and q-axis by other arithmetic processors, without adding a new arithmetic processor for abnormality detection, in a controller which controls a rotary electric machine using a plurality of arithmetic processors . The second arithmetic processor (12) calculates voltage command values for control on rotating coordinate system of d-axis and q-axis, based on current command values acquired from the first arithmetic processor (11); and the first arithmetic processor (11) calculates voltage command values for determination on rotating coordinate system of d-axis and q-axis, based on the current command values, and determines whether or not abnormality occurred in the second arithmetic processor (12), by comparing the voltage command values for control acquired from the second arithmetic processor (12) with the voltage command values for determination.
