A novel neural network intelligent controller for vector controlled induction motor drive

In this paper, a novel neural network intelligent controller is proposed for the vector controlled induction motor. Fuzzy logic controller is interfaced with the three phase induction motor initially. Effectiveness of this fuzzy logic controller with the three phase induction motor is analysed under disturbance environment. It is identified that fuzzy logic controller is not up to the mark in terms of speed tracking. Therefore, neural network based intelligent controller is interfaced with the three phase induction motor. Performance of this proposed neural network controller is analysed in the disturbance environment. At the end, comparison chart is made to know the effectiveness of the proposed neural network controller with the fuzzy logic controller. This comparison chart is delineated for the various control system parameter aspects. It is recognised that the proposed neural network controller works well in the presence of the disturbances. Moreover, this neural network controller operates adroitly for all the necessary working conditions. (C) 2017 The Authors. Published by Elsevier Ltd.
