A flux observe for vector control of an induction machine using fuzzy identification

This work describes a novel flux estimation of a rotor flux oriented by the induction motor drive. A fuzzy modeling is used for flux vector estimation. For vector control (VC), it is necessary to know the instantaneous magnitude of the rotor flux. A method of fuzzy modeling can accurately estimate the rotor flux magnitude. It can estimate the flux response via the fuzzy model training. The accuracy of the present fuzzy modeling method for VC is shown by the simulation result. Our work indicates that the fuzzy modeling may be a feasible alternative to flux estimation method.
