Abstract
In this paper the H ∞ norm approximation of a given stable, proper, rational transfer function by a constant matrix is considered (Zeroth order H ∞ norm approximation problem). The solution method is based on the observation that the H ∞ norm approximation problem can be put into an allpass imbedding problem.Keywords
