Several schemes for plant model identiΓΏcation in closed-loop operation including classical direct method, two-step identiΓΏcation and closed-loop output error algorithms are considered. These methods are analyzed and compared in terms of the bias distribution of the estimates for the case that the no
## We convert the closed-loop identification of nonlinear time-varying plants, with high signal-to-noise ratio, to an open-loop identification problem of an associated Youla-Kucera parameter. The plant must be stabilizable by a known linear, possibly time-varying controller.
The main contribution of this paper is a recursive algorithm for parametric system identification in the presence of both noise and model uncertainties. The estimates provided by this algorithm are not invalidated, after a learning period, by the observed input-output data and the assumed system and
