A theory of the infinite horizon LQ-problem for composite systems of PDEs with boundary control
We study the infinite horizon Linear-Quadratic problem and the associated algebraic Riccati equations for systems with unbounded control actions. The operator-theoretic context is motivated by composite systems of Partial Differential Equations (PDE ...

Multi‐Objective Robust Controller Synthesis With Integral Quadratic Constraints in Discrete‐Time
ABSTRACT This article presents a novel framework for the robust controller synthesis problem in discrete‐time systems using dynamic Integral Quadratic Constraints (IQCs). We present an algorithm to minimize closed‐loop performance measures such as the ℋ∞$$ {\mathscr{H}}_{\infty } $$‐norm, the energy‐to‐peak gain, the peak‐to‐peak gain, or a ...

On Hilbert-Schmidt norm convergence of Galerkin approximation for operator Riccati equations [PDF]
An abstract approximation framework for the solution of operator algebraic Riccati equations is developed. The approach taken is based on a formulation of the Riccati equation as an abstract nonlinear operator equation on the space of Hilbert-Schmidt ...

The solution set of the algebraic Riccati equation and the algebraic Riccati inequality
The author presents a way of parametrizing the set of Hermitian solutions of both the algebraic Riccati equation (ARE) and the algebraic Riccati inequality (ARI), and also provides necessary and sufficient conditions for the existence of a maximal (minimal) solution of the ARE or the ARI, in the whole set of solutions.

The Extended Hamiltonian Algorithm for the Solution of the Algebraic Riccati Equation
We use a second-order learning algorithm for numerically solving a class of the algebraic Riccati equations. Specifically, the extended Hamiltonian algorithm based on manifold of positive definite symmetric matrices is provided.

Algebraic methods for the solution of some linear matrix equations [PDF]
The characterization of polynomials whose zeros lie in certain algebraic domains (and the unification of the ideas of Hermite and Lyapunov) is the basis for developing finite algorithms for the solution of linear matrix equations. Particular attention is

On the Solution of the Rational Matrix Equation X=Q+LX−1LT
We study numerical methods for finding the maximal symmetric positive definite solution of the nonlinear matrix equation X=Q+LX−1LT, where Q is symmetric positive definite and L is nonsingular.
