完全耦合正倒向随机控制系统的线性二次型问题

Linear quadratic problems for fully coupled forward-backward stochastic control systems

Mingshang Hu, Shaolin Ji, Xiaole Xue

摘要:

研究具有不定控制权代价的随机完全耦合正倒向线性二次型(FBLQ)问题的最优控制。为了得到最优控制的状态反馈表达式,我们提出了一种新的解耦方法,得到了一类非Riccati型常微分方程(ODE)。在一定的假设条件下,利用平方完备法证明了所得到的常微分方程解的存在性,并导出了最优控制的状态反馈形式。对于这个FBLQ问题,最优控制依赖于状态过程的整个轨迹。最后给出了一些具体的例子来说明我们的结果。

英文摘要:

This paper is concerned with optimal control of stochastic fully coupled forward-backward linear quadratic (FBLQ) problems with indefinite control weight costs. In order to obtain the state feedback representation of the optimal control, we propose a new decoupling technique and obtain one kind of non-Riccati-type ordinary differential equations (ODEs). By applying the completion-of-squares method, we prove the existence of the solutions for the obtained ODEs under some assumptions and derive the state feedback form of the optimal control. For this FBLQ problem, the optimal control depends on the entire trajectory of the state process. Some sepcial cases are given to illustrate our results.
