Linear-Quadratic Stochastic Stackelberg Differential Games for Jump-Diffusion Systems

Jun Moon

摘要:

研究了具有随机系数的跳扩散系统的线性二次(LQ)随机主从Stackelberg微分对策.首先利用随机最大值原理求解了跟随器的LQ问题,得到了开环最优解的状态反馈表示形式,即积分随机里卡蒂微分方程(ISRDE),并通过平方完备化方法证明了状态反馈型控制是最优的.其次,我们利用变分方法建立了领导者的不定LQ随机最优控制问题的随机最大值原理。然而,为了获得领导者的开环解的状态反馈表示,由于跳跃过程,存在技术挑战。为了克服这一限制,我们考虑两种不同的情况下,其中的状态反馈型最优控制的领导人在ISRDE可以概括的四步计划的特点。最后,在这两种情况下,我们表明,状态反馈表示的开环最优解的领导者和追随者构成的Stackelberg均衡。注意,领导者的(不确定)LQ控制问题是新的和非平凡的,由于耦合FBBACK约束引起的理性行为的追随者。

英文摘要:

This paper considers linear-quadratic (LQ) stochastic leader-follower Stackelberg differential games for jump-diffusion systems with random coefficients. We first solve the LQ problem of the follower using the stochastic maximum principle and obtain the state-feedback representation of the open-loop optimal solution in terms of the integro-stochastic Riccati differential equation (ISRDE), where the state-feedback type control is shown to be optimal via the completion of squares method. Next, we establish the stochastic maximum principle for the indefinite LQ stochastic optimal control problem of the leader using the variational method. However, to obtain the state-feedback representation of the open-loop solution for the leader, there is a technical challenge due to the jump process. To overcome this limitation, we consider two different cases, in which the state-feedback type optimal control for the leader in terms of the ISRDE can be characterized by generalizing the Four-Step Scheme. Finally, in these two cases, we show that the state-feedback representation of the open-loop optimal solutions for the leader and the follower constitutes the Stackelberg equilibrium. Note that the (indefinite) LQ control problem of the leader is new and nontrivial due to the coupled FBSDE constraint induced by the rational behavior of the follower.
