松弛平均场随机控制问题解的存在性和最优性条件

Existence and optimality conditions for relaxed mean-field stochastic control problems

Khaled Bahlali, Meriem Mezerdi, Brahim Mezerdi

摘要:

研究了一类由平均场随机微分方程控制的系统的最优控制问题,其中控制既考虑漂移系数又考虑扩散系数。研究了松弛模型,其中容许控制是测度值过程,松弛状态过程由正交鞅测度驱动,其协方差测度是松弛控制.这是原严格控制问题的自然扩张,我们证明了最优控制的存在性。然后,我们推导出这个问题的最优性必要条件,在两个伴随过程的情况下,放宽控制的已知结果。

英文摘要:

We consider optimal control problems for systems governed by mean-field stochastic differential equations, where the control enters both the drift and the diffusion coefficient. We study the relaxed model, in which admissible controls are measure-valued processes and the relaxed state process is driven by an orthogonal martingale measure, whose covariance measure is the relaxed control. This is a natural extension of the original strict control problem, for which we prove the existence of an optimal control. Then, we derive optimality necessary conditions for this problem, in terms of two adjoint processes extending the known results to the case of relaxed controls.
