چکیده

In this paper, we introduce the doubling transformation, a structure-preserving transformation for symplectic pencils, and present its basic properties. Based on these properties, a unified convergence theory for the structure-preserving doubling algorithms for a class of Riccati-type matrix equations is established, using only elementary matrix theory.

Solving large-scale continuous-time algebraic Riccati equations by doubling

We consider the solution of large-scale algebraic Riccati equations with numerically lowranked solutions. For the discrete-time case, the structure-preserving doubling algorithm has been 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 ] >, with D (1) k and D (2) k being low-ranked and S −1 k being small in dimension. For t...

A new two-phase structure-preserving doubling algorithm for critically singular M-matrix algebraic Riccati equations

Among numerous iterative methods for solving the minimal nonnegative solution of an M -matrix algebraic Riccati equation, the structure-preserving doubling algorithm (SDA) stands out owing to its overall efficiency as well as accuracy. SDA is globally convergent and its convergence is quadratic, except for the critical case for which it converges linearly with the linear rate 1=2. In this paper...

Structure-preserving algorithms for Hermitian solutions of algebraic Riccati equations

In this paper, we propose structure-preserving algorithms for the computation of Hermitian solutions of continuous/discrete-time algebraic Riccati equations. Under assumptions that partial multiplicities of purely imaging and unimodular eigenvalues (if any) of the associated Hamiltonian and symplectic pencil, respectively, are all even, we prove that the developed structure-preserving algorithm...

A Structured Doubling Algorithm for Discrete-time Algebraic Riccati Equations with Singular Control Weighting Matrices

In this paper we propose a structured doubling algorithm for solving discrete-time algebraic Riccati equations without the invertibility of control weighting matrices. In addition, we prove that the convergence of the SDA algorithm is linear with ratio less than 1 2 when all unimodular eigenvalues of the closed-loop matrix are semisimple. Numerical examples are shown to illustrate the feasibili...
