A fast algorithm to compute the $$H_{\infty}$$-norm of a transfer function matrix. (English) Zbl 0699.93021
Summary: A fast algorithm is presented to compute the $$H_{\infty}$$-norm of a transfer function matrix, based on the relation between the singular values of the transfer function matrix and the eigenvalues of a related Hamiltonian matrix. The norm is computed with guaranteed accuracy. A very simple method to compute a rather close lower bound on the $$H_{\infty}$$-norm is given.
