Abstract
Provided is a control device for a rotary machine including: a power feed unit configured to feed electric power in accordance with a power feed command to a rotary machine; a rotation-state detecting unit configured to detect a rotation state of the rotary machine; a torque detecting unit configured to detect an output torque output from the rotary machine; an abnormality determining unit configured to determine an abnormality in the rotation-state detecting unit or the torque detecting unit; and an excitation-command generating unit configured to generate an excitation command for oscillating the rotary machine, in which the power feed command is generated based at least on the excitation command, and the abnormality determining unit is configured to determine the abnormality in the detecting units based on a response of the rotation state and a response of the output torque to the excitation command.
