The Hankel Matrix Solution to a System of Quaternion Matrix Equations

2020 Chinese Control And Decision Conference (CCDC), 2020
The solution of matrix equations and the optimal approximation problem play an important role in linear optimal control, parameter identification, structural vibration, aviation and other fields. Hankel matrix is kind of matrix with special structure and wide application. In this paper, the problem of Hankel constraint solution to the system [AXB CXD]=[

Periodic Systems: Controllability and the Matrix Riccati Equation

SIAM Journal on Control and Optimization, 1978
Referring to recently published results, a few problems apparently playing a basic role in periodic control theory are discussed in this paper. Specifically, the problems dealt with are the controllability of linear periodic systems and the existence of periodic solutions for periodic matrix Riccati equations.

Solution of the Lyapunov matrix equation for a system with a time‐dependent stiffness matrix

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2003
AbstractThe stability of the linearized model of a rotor system with non‐symmetric strain and axial loads is investigated. Since we are using a fixed reference system, the differential equations have the advantage to be free of Coriolis and centrifugal forces.

Matrix Riccati equations and systems structure

1973 IEEE Conference on Decision and Control including the 12th Symposium on Adaptive Processes, 1973
A new algorithm for solving discrete time linear-quadratic control problems is given. This algorithm is shown to be a special case of the "structure algorithm" used for characterizing properties of linear systems. It is also shown to be related to the Chandrasekhar-type equations recently introduced by Kailath.

A system of equations with a tridiagonal coefficient matrix

Applied Mathematics and Computation, 2004
The goal of the paper is to show that for a linear system of equations \(AX=C\), where the coefficient matrix \(A\) is tridiagonal, the algorithms used by \textit{M. El-Mikkawy} in [Appl. Math. Comput. 139, No. 2--3, 503--511 (2003; Zbl 1078.65533)] can be improved in the case when \(A\) is invertible, the system being equivalent with a linear system ...

A Note on Kronecker Matrix Products and Matrix Equation Systems

SIAM Journal on Applied Mathematics, 1969
where B' is the transpose of B. It has been shown that Definition 1 and Theorem 1 can fruitfully be applied to problems of matrix differentiation [2]. In this note it will be shown that they can be applied to a more general class of linear matrix equations, including linear matrix differential equations.
