平均场偏微分方程的部分观测最优控制

Partially Observed Optimal Control for Mean-Field SDEs

Maonin Tang, Qingxin Meng

摘要:

本文研究了部分观测下的平均场型随机最优控制问题,其中状态方程由受控非线性平均场随机微分方程控制,且允许观测噪声进入状态方程,观测系数不仅依赖于控制过程,而且依赖于控制过程的概率分布.在系数的标准假设下,通过对偶分析和凸变分,分别建立了强意义和弱意义下的最优控制的最大值原理。作为应用,详细研究了平均场型部分可观测线性二次型控制问题,利用随机最大值原理和经典的平方完备技术,得到了部分可观测最优控制的对偶刻画和状态反馈表示.

英文摘要:

In this paper, we are concerned with a stochastic optimal control problem of mean-field type under partial observation, where the state equation is governed by the controlled nonlinear mean-field stochastic differential equation, moreover the observation noise is allowed to enter into the state equation and the observation coefficients may depend not only on the control process and but also on its probability distribution. Under standard assumptions on the coefficients, by dual analysis and convex variation, we establish the maximum principle for optimal control in a strong sense as well as a weak one, respectively. As an application, a partially observed linear quadratic control problem of mean-field type is studied detailed and the corresponding dual characterization and state feedback presentation of the partially observed optimal control are obtained by the stochastic maximum principles and the classic technique of completing squares.
