Hankel norm computation for pseudorational transfer functions

This paper gives a new computational method of the Hankel norm for the class of pseudorational transfer functions. This class and the obtained method have the advantage that they allow us to deal with a large class of systems that were not treated in the literature, for example, general retarded or neutral delay differential systems. An easily computable approximating sequence is obtained, which converges to the Hankel norm. Examples are given to illustrate the result.
