On computing the spectral radius of the Hankel plus Toeplitz operator
Jyh‐Ching Juang, EDMOND A. JONCKHEERE · IEEE Transactions on Automatic Control · 1988
The square root of the spectral radius of the Hankel plus Toeplitz operator has been shown to be the achievable performance of the mixed-sensitivity H/sup infinity / design. The computation of the spectral radius is the bottleneck in the synthesis of the H/sup infinity / controller. In this paper, the spectral properties of the Hankel plus Toeplitz operator are investigated. A finite procedure for computing the spectral radius of the Hankel plus Toeplitz operator is proposed.>
