Abstract
The central solution for the commutant lifting theorem is used to solve mixed H2-H∞ tangential interpolation problems. These include an H2-H∞ tangential Carathéodory interpolation problem, an H2-H∞ tangential Nevanlinna-Pick interpolation problem and an H2-H∞ tangential Hermite-Fejer interpolation problem. Explicit computational formulas in terms of state space realizations are given.
