A LIM simulation model using MATLAB/S-Function.
The model is established with single sided LIM mathmatical model. The mathmatical model is given below.
votage equation:
flux equation:
and the movement equation:
from the votage equation, we got the current equation:
from the flux equation, we got the flux state equation:
the S-Function model is written as lim_model.m.
the simulink model is lim_s_function.slx.
then the LIM S-Funtion model looks like this:
the open-loop simulation:
The parameters of LIM is listed below.
