Al~traet--This paper deals with the identification of linear constant dynamical systems when formalized as a rational approximation problem. The criterion is the 12 norm of the transfer function, which is of interest in a stochastic context. The problem can be expressed as nonlinear optimization in
We consider the nonlinear approximating family \(R_{m}^{n}\) of rational expressions over a real interval. In the \(L^{p}\) norms, \(l<p<\infty\) non-normal elements of this family cannot arise as best approximations to functions outside the family. In the \(L^{\prime}\) case, Dunham (1971) has show
