Mathematical modelling of Linear Induction Motor with and without considering end effects using different reference frames

Abstract

In this paper, a mathematical model based on d-q axes equivalent circuit is used to describe the dynamic behavior of Linear Induction Motor (LIM) with and without considering end effects. The model is simulated using two different reference frames namely stationary reference frame and synchronously rotating reference frame for better understanding of the transient and steady state behavior of the LIM. This transient and steady state analysis helps in deciding the reference frame based on the problem to be resolved, variables to be studied and the machine type either single-machine or multi-machine system. The model is simulated using MATLAB/SIMULINK tools as it is the sophisticated way of implementing the dynamic equations using function blocks. The control for Linear Induction Motor like vector control, position control and sliding model control can be applied to this model.
