Singular Riccati equations stabilizing large-scale systems

where A and B are n× n and n× p real matrices which are known, and xi and ui are vectors of dimension n and p respectively. The stabilization of the system requires the computation of a p×n feedback matrix F such that all eigenvalues of A−BF are inside the unit circle and therefore the system defined by replacing A with A−BF is stable. For small and moderate values of n, F can be computed via p...

A Pod Projection Method for Large-scale Algebraic Riccati Equations

The solution of large-scale matrix algebraic Riccati equations is important for instance in control design and model reduction and remains an active area of research. We consider a class of matrix algebraic Riccati equations (AREs) arising from a linear system along with a weighted inner product. This problem class often arises from a spatial discretization of a partial differential equation sy...

Solving Large-Scale Nonsymmetric Algebraic Riccati Equations by Doubling

We consider the solution of the large-scale nonsymmetric algebraic Riccati equation XCX − XD − AX + B = 0, with M ≡ [D,−C;−B,A] ∈ R(n1+n2)×(n1+n2) being a nonsingular M-matrix, and A,D being sparse-like (with the products A−1v, A−>v, D−1v and D−>v computable in O(n1) or O(n2) complexity, for some vector v) and B,C are low-ranked. The structure-preserving doubling algorithm by Guo, Lin and Xu (2...

BDF Methods for Large - Scale Differential Riccati Equations ∗

We consider the numerical solution of differential Riccati equations. We review the existing methods and investigate whether they are suitable for large-scale problems arising in LQR and LQG design for semi-discretized partial differential equations. Based on this review, we suggest an efficient matrix-valued implementation of the BDF for differential Riccati equations.

Solving Large-Scale Discrete-Time Algebraic Riccati Equations by Doubling

We consider the solution of large-scale discrete-time algebraic Riccati equations with numerically low-ranked solutions. The structure-preserving doubling algorithm will be adapted, with the iterates for A not explicitly computed but in the recursive form Ak = A 2 k−1 − D (1) k S −1 k [D (2) k ] >, where D (1) k and D (2) k are low-ranked with S −1 k being small in dimension. With n being the d...
