摘要 |
A rotary electric machine controller according to the present application includes: a superimposer for superimposing a high-frequency signal on one of a voltage and a current of a motor having saliency; an estimator for calculating an estimate value of a magnetic-pole position of a rotor included in the rotary electric machine based on a high-frequency component appearing in the other one of the voltage and the current of the rotary electric machine; a retainer for retaining information relating to a correction amount corresponding to the estimate value of the magnetic-pole position of the rotor; and a corrector for correcting the estimate value of the magnetic-pole position of the rotor based on the information relating to the correction amount. |

1. A rotary electric machine controller, comprising:
a superimposer for superimposing a high-frequency signal on one of a voltage and a current of a rotary electric machine having saliency; an estimator for calculating an estimate value of a magnetic-pole position of a rotor included in the rotary electric machine based on a high-frequency component appearing in the other one of the voltage and the current of the rotary electric machine; a retainer for retaining correction amount relating values which are different from each other for at least two points of the magnetic-pole position of the rotor; and a corrector for acquiring one of the correction amount relating values retained by the retainer corresponding to the estimate value of the magnetic-pole position of the rotor and correcting the estimate value of the magnetic-pole position of the rotor based on the acquired one of the correction amount relating values. |
