| Abstract |
The paper proposes a novel rotor flux estimator with capability of instantaneous adaptation to the actual
saturation level in the machine. The estimator is based on measurements of stator currents and rotor speed and is obtained from a recently introduced saturated induction machine model in which stator current and rotor flux d-q axis components arc selected as state-space variables. Pcrfommnce of the estimator is verified by simulation. The complexity of the estimator and requirements regarding determination of appropriate magnetising curve of the machine are compared with other existing approaches. Favourable conclusions are drawn with respect to the estimator proposed in this paper. |
