    Dear Aleksei

    I appreciate your efforts for designing such a magnificent toolbox. Could you please tell how you utilized filtfilt command in identification of thermal system, example 6.2.2 of tour thesis. In fact, I am working on fractional system identification of electrical furnace, and the problem is here that the error signal is very noticeable, the difference between integer system and fractional one. It came in my mind that the input data had been ‘detrend’ed in MATLAB. When I was trying to consist ‘fidata’, there is no ‘detrend’ procedure, so my conclusion is that that is the source of this noticeable error.

    thanks in advance

      Here are two points.
      1. filtfilt was used to remove the noise from the measurement. This is not, strictly speaking, necessary.
      2. In the identification procedure we assume, that the state is initially zero. So if there is an offset (e.g. environment temperature), it should be removed, but, of course, considered in the model!

    Dear Aleksei

    Do you have any example(s) of FOID for power electronics – Boost, Buck or Inverter converter dynamic behaviour (Bifurcation and Chaos mapping)?

      I have seen your question in another comment thread, but did not have time to answer; No, I do not have any examples from this particular field yet. We have research plans covering this, though. Hopefully, you will see some updates soon.
