MATLAB: I have no idea if that possible to in Simulink or not , please help

switch reluctance motor curve simulink

This is flux linkage-current curve for switch reluctance motor.
Anyone can get this graph (inside block parameters > plot magnatizing curve)
I want to get a formula flux linkage as a function of current for the yellow line(first line), and the blue line (last one)
is that possible??

Best Answer

Given a curve and try to figure out an approximate formular is called curve fitting. Don't do it in Simulink. Do it offline in MATLAB.
