离散广义代数Riccati方程的降阶和解的结构

The Discrete-Time Generalized Algebraic Riccati Equation: Order Reduction and Solutions' Structure

Lorenzo Ntogramatzidis, Augusto Ferrante

摘要:

本文讨论了如何将最优控制和最优滤波问题中的约束广义离散时间代数Riccati方程分解为两部分,对应于每个解X的加法分解X= X 0 +D:第一部分是加数X 0的显式表达式,它是所有解的公共加数,不依赖于特定的X。第二部分可以是一个降阶离散时间正则代数Riccati方程,其相关的闭环矩阵是非奇异的,或对称Stein方程。

英文摘要:

In this paper we discuss how to decompose the constrained generalized discrete-time algebraic Riccati equation arising in optimal control and optimal filtering problems into two parts corresponding to an additive decomposition X=X0+D of each solution X: The first part is an explicit expression of the addend X0 which is common to all solutions, and does not depend on the particular X. The second part can be either a reduced-order discrete-time regular algebraic Riccati equation whose associated closed-loop matrix is non-singular, or a symmetric Stein equation.
