 Hello all,


 is it possible to derive the transfer function from jsbsim fdm
 coefficients. I know the way to calculate the parameters like Clalpha
 for a operation point. But for a root locus analyse I need the transfer
 function (Root locus is used to calculate the PID-Controller parameter)
 I would like to start with a function, which descripe the dependency of
 climb to elevator deflection

 climb = f(elevator-deflection)

 I want to use SCILAB (free matlab ;)) to analyse the close-loop behaviour.


 Any help will be appreciated


 Kind regards

I'm not any good at this, but will converting the state space of the
logitudinal dynamics into a transfer function help?  Again, I'm not
sure.
