Application of adaptive neuro fuzzy inference system on the development of the observer for speed sensor less induction motor

Abstract

Direct field-oriented induction motor drive system need rotor flux observer and rotor angular speed identifier. ANFIS (adaptive neuro fuzzy inference system) used for identifying parameter dynamics and system variable estimation, linear or nonlinear. ANFIS with backpropagation learning algorithm has applied to estimate flux rotor and identify rotor angular speed of three-phase induction motor.
