一类离散时间线性调节器问题的基于极大加的基本解

A max-plus based fundamental solution for a class of discrete time linear regulator problems

Huan Zhang, Peter M. Dower

摘要:

有效的Riccati方程为基础的技术的近似解的离散时间线性调节器问题的限制,在其应用程序的问题与二次终结支付。在需要非二次终结支付的情况下,这些技术由于所涉及的伴随的非二次值函数而失败。为了计算这些非二次值函数,通常需要直接求助于动态规划,其形式为值函数的基于网格或基于元素的迭代。这些迭代在问题维度和时间范围方面具有较差的可扩展性。本文提出了一种新的基于最大加的方法,用于求解具有非二次型支付的离散时间线性调节器问题的近似解。这种新方法的基础是新的基本解的发展,这样的线性调节器的问题,通过最大加对偶。与典型的基于网格的方法相比,在应用这种新的最大加方法中观察到计算工作量的大幅减少。一些简单的例子来说明这一点和其他意见。

英文摘要:

Efficient Riccati equation based techniques for the approximate solution of discrete time linear regulator problems are restricted in their application to problems with quadratic terminal payoffs. Where non-quadratic terminal payoffs are required, these techniques fail due to the attendant non-quadratic value functions involved. In order to compute these non-quadratic value functions, it is often necessary to appeal directly to dynamic programming in the form of grid- or element-based iterations for the value function. These iterations suffer from poor scalability with respect to problem dimension and time horizon. In this paper, a new max-plus based method is developed for the approximate solution of discrete time linear regulator problems with non-quadratic payoffs. This new method is underpinned by the development of new fundamental solutions to such linear regulator problems, via max-plus duality. In comparison with a typical grid-based approach, a substantial reduction in computational effort is observed in applying this new max-plus method. A number of simple examples are presented that illustrate this and other observations.
