Firefly algorithm optimization of high efficiency induction machine using inverse problem

Abstract

The design of electromagnetic actuators is increasingly complex and needs to be more efficient on a panel of criteria increasingly wide. The challenge offered to design engineers is great. It is therefore essential to integrate new tools and methodologies in the design process to meet this challenge. This paper presents a Firefly Algorithm (FA) for optimizing the Induction Motor (IM) design by using an inverse problem formulation to increase efficiency and minimizing rotor, stator and iron losses. Effectiveness and robustness of the proposed approach are verified by a comparison with those obtained by conventional and direct approaches. The obtained results show that the efficiency of the motor is increased by 1.15% and the losses are reduced by 5% compared to those obtained by both direct problem and conventional methods. © 2018 Praise Worthy Prize S.r.l.-All rights reserved.
