✦ Synopsis


For a class of inΓΏnite-dimensional systems we obtain a simple frequency domain solution for the suboptimal Nehari extension problem. The approach is via J -spectral factorization, and it uses the concept of an equalizing vector. Moreover, the connection between the equalizing vectors and the Nehari extension problem is given.

In this paper, for infinite-dimensional systems characterized by unknown and unbounded system operators, some sufficient conditions for robust disturbance-rejection problems to be solvable are studied in the framework of the so-called geometric approach.
