LQ最优控制中的广义离散代数Riccati方程

The Generalised Discrete Algebraic Riccati Equation in LQ optimal control

Augusto Ferrante, Lorenzo Ntogramatzidis

摘要:

本文研究了由经典无限时域线性二次控制问题的解所产生的广义离散代数Riccati方程的解的性质。特别是,几何分析用于研究广义Riccati方程的解决方案和输出为零的子空间的基础系统和相应的可达子空间之间存在的关系。这种分析揭示了一个子空间的存在,发挥了重要作用,在解决相关的最优控制问题,这是反映在相应的扩展辛束的广义本征结构。在建立本文的主要结果时,还讨论并解决了离散李雅普诺夫方程和谱分解的若干辅助问题。

英文摘要:

This paper investigates the properties of the solutions of the generalised discrete algebraic Riccati equation arising from the solution of the classic infinite-horizon linear quadratic control problem. In particular, a geometric analysis is used to study the relationship existing between the solutions of the generalised Riccati equation and the output-nulling subspaces of the underlying system and the corresponding reachability subspaces. This analysis reveals the presence of a subspace that plays an important role in the solution of the related optimal control problem, which is reflected in the generalised eigenstructure of the corresponding extended symplectic pencil. In establishing themain results of this paper, several ancillay problems on the discrete Lyapunov equation and spectral factorisation are also addressed and solved.
