A Comprehensive Approach to Investigate Parameters Sensitivity of Three Phases Induction Motors using MATLAB/Simulink

Abstract

This paper present the schematic scheme to evaluate the effects of changing basic parameters of 3 phases induction motors. The proposed approach has been applied to four motors in varied range of power. Dynamic analysis of a three-phases induction motor is studied and the machine dynamics are presented by a set of time-varying differential equations. The analysis and simulation of the mentioned method are shown and comparison of results has been done. The obtained shows that there is a significant difference between dynamic behaviour of low power and high power simulated machines.
