Fuzzy logic and firefly algorithm based hybrid system for energy efficient operation of three phase induction motor drives

Abstract

Background/Objectives: Three phase induction motors have been the workforce for several industrial, manufacturing,propulsion and transportation applications for the past several years. Energy efficient operation of induction motors is theimportant task in industries.The objective of the present paper is to provide energy efficient operation of induction motorsusing soft computing techniques. Methods/Statistical analysis: A fuzzy logic and firefly algorithm based hybrid techniqueis used for performance improvement of a.c.voltage controller fed three phase induction motor drives. Simulation is doneby using matlab software. Findings: It is shown that the conventional search method for reaching the best efficiency pointhas got many drawbacks. These demerits are overcomed using the proposed softcomputing techniques. Application/Improvements: Improvement in motor efficiency and power factor is achieved and the motor always operates in theenergy efficient region.
