Hello, I did some measurements and data analysis on a system. Now I want to let scilab calculate a transfer function with armax algorithm but I'm running into problems. input_short is the input vector and the same with output_short. Then I do: [arc,resid]=armax(8,5,output_short,input_short) [z]=arsimul(arc,input_short);
And afterwards I'm plotting the real output and the simulated one: plot(scalar,[z' output_short']); Now here are four different value pairs of the plot: <http://mailinglists.scilab.org/file/n4030499/SimulatedVsReal.png> And here is the real system with input and output: (Is longer, the above is only a extract) <http://mailinglists.scilab.org/file/n4030499/real_system.png> Now I really don't know what to do to get satisfying results? Anyone got an advice? Thank you so much!
