- Abstract
- This paper proposes a novel rotor position error calculation method for high-frequency signal-injected sensorless control. The rotor position error using the conventional modulation method can be only measured up to ±45°. In addition, when the rotor position estimation error is not sufficiently small, the small angle approximation in no longer valid. To overcome these problems, this study introduces a new rotor position error calculation method using the rotating matrix. In this study, the position error measurement range of the proposed method is extended from ±45° to ±90°. The linearity between the real rotor position error and the estimated error is maintained by nearly 90°. These features of the proposed method improve the performance of the sensorless control. The validity of the proposed method is verified by simulations and experiments.
