| Outline of Final Research Achievements |
By introducing the notion of quasi Hankel operators, studies on Hankel norm are extended to sampled-data systems and periodic systems. It is studied whether the values of the norms of quasi Hankel operators called the quasi Hankel norms attain their maximum over a single (half-open) interval corresponding to the period of the system. It is also studied how to compute the Hankel norm defined as the supremum of the quasi Hankel norms. The relationship between the quasi Hankel and Hankel operators and the well-known H2 norm is studied, and the discrete-time controller synthesis method for minimizing the L-infinity/L2 Hankel norm is derived.
