Some results on the finite-dimensional approximation of the algebraic Riccati equation in Hilbert spaces.

ABSTRACT
This paper deals with the problem of approximating the infinite-dimensional algebraic Riccati equation, considered as an abstract equation in the Hilbert space of Hilbert-Schmidt operators. Two kinds of approximating schemes are proposed. The first one exploits the already established approximability of the corresponding dynamical Riccati equation togheter with its time convergence toward the steady-state. The second method considers a particular sequence of finite-dimensional linear equations whose solutions is proved to converge toward the exact steady-state solution of the original problem.
