F. De Bruyne et al., Gradient expressions for a closed-loop identification scheme with a tailor-made parametrization, AUTOMATICA, 35(11), 1999, pp. 1867-1871
In this paper, we present gradient expressions for a closed-loop parametric
identification scheme. The method is based on the minimization of a standa
rd identification criterion and a parametrization that is tailored to the c
losed-loop configuration. It is shown that for both linear and nonlinear pl
ants and controllers, the gradient signals can be computed exactly. (C) 199
