摘要:

本文研究完全耦合的正向-反向随机系统的一类风险敏感最优控制问题。控制变量进入状态方程的扩散项,且控制域不一定凸。在未假设值函数光滑的情况下,获得了新的全局最大值原理。最大条件以及一阶和二阶伴随方程严重依赖于风险敏感参数。本文讨论了具有完全耦合线性正向-反向随机系统和指数二次成本泛函的最优控制问题。通过 Girsanov 定理和配方法,借助风险敏感 Riccati 方程,获得了最优反馈控制和最优成本。利用 Picard-Lindelöf 定理给出了耦合风险敏感 Riccati 方程的局部可解性结果。

英文摘要:

This paper is concerned with a kind of risk-sensitive optimal control problem for fully coupled forward-backward stochastic systems. The control variable enters the diffusion term of the state equation and the control domain is not necessarily convex. A new global maximum principle is obtained without assuming that the value function is smooth. The maximum condition, the first- and second-order adjoint equations heavily depend on the risk-sensitive parameter. An optimal control problem with a fully coupled linear forward-backward stochastic system and an exponential-quadratic cost functional is discussed. The optimal feedback control and optimal cost are obtained by using Girsanov's theorem and completion-of-squares approach via risk-sensitive Riccati equations. A local solvability result of coupled risk-sensitive Riccati equations is given by Picard-Lindel$\ddot{o}$f's Theorem.
