ANFIS Based Intelligent Control of Vector Controlled Induction Motor Drive

This paper presents Adaptive Neuro-Fuzzy Inference System (ANFIS) based intelligent control of vector controlled induction motor drive. The proposed intelligent control scheme consists of sensorless adaptive neuro-fuzzy speed controller with speed estimation based on adaptive neuro-fuzzy inverse model. The proposed neuro-fuzzy speed controller incorporates fuzzy logic algorithm with a five-layer artificial neural network (ANN) structure. The conventional PI speed controller is replaced by Adaptive Neuro-Fuzzy Inference System (ANFIS), which tunes the fuzzy inference system with hybrid learning algorithm. This makes fuzzy system to learn. The structure of speed estimator is also same as speed controller but it incorporates inverse model identification algorithm for speed estimation. The performance of the proposed scheme is investigated at different operating conditions. The simulation study indicates robustness and suitability of drive for high performance drives applications.
