Abstract

This paper presents a novel grammatical flux estimator for sensorless AC-drives. The proposed methodology does not require the integration of the standard voltage model neither the exact knowledge of the system parameters. Assuming the flux estimator as a linguistic source, producing a certain language, a grammatical inference algorithm is used to extract the productions that govern the grammar representing that language. The formalism of the developed formal language based control algorithm is presented. The inherent non-linear characteristics of the grammar productions make it possible to obtain accurate flux estimation. Application results are presented in order to show the effectiveness of the proposed methodology.
