Development of Microcontroller-Based Speed Controller for Three-Phase Induction Motor using Fuzzy Logic Technique
Abstract
This paper presents an intelligent control technique based on fuzzy logic to control the speed of a three-phase induction motor. There are numerous applications of induction motors in the industry due to their features, such as simplicity in design, cost-effectiveness, and durability. Most of these industrial applications require intelligent control. The induction motor was modelled with a rotating reference frame. The fuzzy logic controller was designed with an MSP430F149 microcontroller for the application requiring speed control. The model of the induction motor was simulated using MATLAB/SIMULINK® version 2013a software. The system's performance was evaluated using a conventional PI controller and fuzzy logic controller. The simulation results show the transcendency of the fuzzy logic controller for indirect vector control of the speed of the three-phase induction motor.
