On a class of irrational two-block Nehari problems with H/sup /spl infin// control applications

Shows how to obtain explicit solutions for a class of irrational two-block Nehari problems using the Krein space approach of Ball and Helton (1983). The author shows that the solutions can be obtained by solving a system of linear equations. The results are applied to solve the H/sup /spl infin// optimal mixed sensitivity control problem for two classes of unstable infinite dimensional systems with irrational weighting functions.<
