Efficiency Improvement of Three Phase Induction Motor Using Artificial Intelligent Technique

Induction Motors have many applications in the industries because of the low maintenance and robustness of induction motors. Most of these applications need fast and smart speed control system. This work presents efficiency maximization of three phase induction motor based on Fuzzy logic approach for an indirect vector controlled motor for high performance. The analysis, design and simulation of the fuzzy logic controller for indirect vector control Induction Motor are carried out based on Fuzzy set theory. Induction Motor is modelled in synchronous reference frame in terms of dq form. In order to achieve maximum performance and energy saving the efficiency maximization of Induction Motor is the main issue. This work introduces efficiency maximization by reducing the core losses. The model is carried out using Matlab/Simulink computer package. The simulation results show the superiority of the fuzzy logic controller in controlling three-phase induction motor with indirect field oriented control technique.
