Fuzzy Based Real Time Control of Induction Motor Drive

Abstract

Due to advancement in power electronics and micro computing, the control of the induction machines has considerable development that lead to the possibility of high performance real time implementation. The most popular algorithm for the control of a three-phase induction motor is the v/f control approach using a natural Pulse-Width Modulation PWM) technique to drive a Voltage Source Inverter (VSI). But the performance of electric drives requires decoupled torque and flux control. The most widely used controllers in industrial applications are PI controllers because of their simple structure and good performance in a wide range of operating conditions. PI and Fuzzy Logic controllers have been designed and developed using MATLAB/SIMULINK. Prototype model is developed to validate the effectiveness of the PI and Fuzzy control of induction motor drive using dSPACE DS1104 controller. The performance of the SVPWM based induction motor in open loop and closed loop is presented with simulation. Fuzzy Logic (FL) and Conventional PI controllers have been practically implemented using SVPWM based VSI fed induction motor in open loop mode. The real time performance of Fuzzy based induction motor is presented by validating simulation results with the hardware results.
