I try to estimate a system transfer function by hand calculation from a bode plot data but I could not succeed yet and I need someone help.
it will be appreciated if anyone explains or refer me to a source where I can learn to estimate the TF with Matlab tools/codes (I couldn't do it with system identification toolbox)
