Abstract: In a system for controlling a rotary machine, a circuit outputs an AC voltage to be applied to a rotary machine. A storage stores therein measurement-error information indicative of a measurement error of the measuring unit. A torque-feedback adjuster manipulates a phase of the output voltage of the circuit based on the rotational angle of the rotary machine measured by a measuring unit and the measurement-error information to adjust a torque of the rotary machine to a request torque. The phase is obtained from information fed back from the rotary machine. An abnormality determiner determines whether there is an abnormality to disable using accurate measurement-error information. A limiter limits adjustment of the torque of the rotary machine to the request torque by the torque-feedback adjuster when it is determined that there is an abnormality to disable using accurate measurement-error information.
