Hi,
When I do system ID based on time domain data and frd data, I am very curious how OE or tfest deal with frd data? I know those functions use some least square methods to ID. If we only have frd data, how "OE" uses these complex number to do? Thanks.
Best regards, Haiming

This paper by Lennart Ljung might be helpful.It pretty much answers your question.

Hi Arkadiy,
Thank you so much. This paper is very good to understand frequency domain identification. But I still have a question about your "OE" function. If I only have frd complex number data, how does "OE" use this frd data to generate input and output frequency data? Thanks.
Best regards, Haiming
