Abstract :
The authors consider an interpolation approach for identification in H∞. In particular, the Nevanlinna Pick interpolation theorem is used to derive the identified model. A tuned nonlinear interpolation algorithm is proposed and the resulting error bound in the H∞ norm is derived. The proposed approach has the advantage that the identified model is in the same set of the unknown, true systems. This is different from the existing results where there is no such guarantee
