WebA new method for closed-loop identification that allows fitting the model to the data with arbitrary frequency weighting is described and analyzed. Just as the direct method, this new method is applicable to systems with arbitrary feedback mechanisms. WebJun 15, 2014 · The main thing with closed-loop id is to use a structure that has a rich noise structure; ssest , bj, armax commands are some options. How can I best identify the unstable plant and verify the model using the system identification toolbox? Unstable id is fundamentally hard since any small errors owing to noise on wrong structure are amplified.
