Abstract
A rotary machine control apparatus controlling a drive of a rotary machine that has multiple winding groups is provided. The rotary machine control apparatus includes electric power converters in multiple systems, a failure detection portion, and a control portion. An electric power converter has switching elements in an upper arm and a lower arm and converts DC power. The failure detection portion detects a failure of an electric power converter or a winding group. The control portion calculates a current command value and a maximum current limit value, and controls an output to the electric power converter. The control portion stops the output to the electric power converter in a failure system, and the control portion increases the maximum current limit value with respect to the output to an electric power converter in a normal system.
