Approximation of Solutions of Riccati Equations [PDF]
SIAM Journal on Control and Optimization, 2005 This paper deals with two interrelated issues. One is an invariant subspace approach to finding solutions for the algebraic Riccati equation for a class of infinite dimensional systems. The second is approximation of the solution of the algebraic Riccati equation by finite dimensional approximants.
