摘要:

在马尔可夫框架下,研究了一类平均场随机微分方程的时间不一致线性二次型最优控制问题。开环平衡控制及其特定的闭环表示介绍和特点,通过变分思想。揭示了几个有趣的功能和耦合Riccati方程系统的推导。与一般的随机微分方程的模拟最优控制问题相比,状态方程中的平均场项是引起时间不一致性的另一个原因,这促使我们对上述两个概念进行新的定义。一个有趣的结果,这是几乎平凡的对应问题的SDES,并发挥重要作用,在以前的特征。作为应用,讨论了开环平衡控制的唯一性。

英文摘要:

In this paper, a class of time inconsistent linear quadratic optimal control problems of mean-field stochastic differential equations (SDEs) is considered under Markovian framework. Open-loop equilibrium controls and their particular closed-loop representations are introduced and characterized via variational ideas. Several interesting features are revealed and a system of coupled Riccati equations is derived. In contrast with the analogue optimal control problems of SDEs, the mean-field terms in state equation, which is another reason of time inconsistency, prompts us to define above two notions in new manners. An interesting result, which is almost trivial in the counterpart problems of SDEs, is given and plays significant role in the previous characterizations. As application, the uniqueness of open-loop equilibrium controls is discussed.
