Wiener--Hopf Factorization Indices and Infinite Structure of Rational Matrices
A. Amparan, Silvia Marcaida, Ion Zaballa · SIAM Journal on Control and Optimization · 2004
The relationship between the infinite structure and the Wiener--Hopf factorization indices of polynomial matrix representations of controllable systems is investigated. On the way, local Wiener--Hopf factorization indices must be defined. In addition, the finite and infinite structure of a rational matrix is characterized given its Wiener--Hopf factorization indices.
