Performance analysis of Average-value based modeling of Field-oriented-controlled Induction Motor Drive System in real-time environment

Abstract

Appropriate modeling plays an important role for analyzing the behavior of any system for its particular application. Therefore, in this work, average modeling of three-phase squirrel cage induction motor and three-phase pulse-width modulated inverter is proposed and used for analyzing the dynamic control performance of induction machine drive system using field-oriented-control strategy for reducing the computational effort in MATLAB/SIMULINK environment, also termed as offline environment. The rotor reference frame is used for inverter as well as for induction machine. The simulation results obtained with this proposed model is compared with well established detailed model. This comparison reveals that the computational time is reduced 10 times approx. while showing the similar control performance of the drive system with this proposed technique. Further, this proposed model is transformed into real-time model using FPGA based simulator i.e. OPAL RT-4510 for its validation as well as for its practical implementation.
