Dasgupta, SouraAnderson, Brian D.O.2025-03-222025-03-22Scopus:0030264543https://dspace-test.anu.edu.au/handle/1885/733728508It has recently been shown that the identification of a linear time-invariant plant using closed-loop measurements with a known linear controller can be effectively tackled by regarding the unknown plant as a member of the set of all plants stabilized by the known linear controller. This set is parametrized by a Youla-Kucera parameter, itself a stable transfer function which, it turns out, can be identified using open-loop techniques. This paper generalizes the parametrization idea to nonlinear plants, and treats identification of nonlinear plants.AcX,lr,t~lr~l~ern~nr\--S.
