| Abstract |
It is proposed in this paper a method to compute gains of induction motor flux observers, based on
fuzzy logic associated to a theoretical sensitivity analysis. The theoretical analysis, taking the
magnetic saturation into account, allows to study the observer sensitivity to all parameter
uncertainties. The fuzzy logic associated to the theoretical analysis allows to determine observer gains
which optimize together dynamics and sensitivity criteria. Although the theoretical sensitivity analysis
may be developed for observers in any reference frame, the proposed method is applied in this paper
respectively to a reduced and a full order flux observers based on the Park model in the stator
reference frame only. The proposed method is validated by experiments on a 750W induction motor. |
