摘要

研究了一类控制平均平均场随机大种群系统的动态优化问题。对于每个智能体,状态系统由一个具有个体噪声和共同噪声的线性平均场随机微分方程(MF-SDE)控制,并且代价函数中的权重系数可以是不定的。分散最优策略的特征是随机哈密顿系统,即代数方程和平均场正反向随机微分方程(MF-FBSDE)。应用解耦方法,进一步通过两个Riccati方程得到分散最优策略的反馈表示。导出了随机哈密顿系统和Riccati方程在不定条件下的可解性。利用分离技术讨论了控制平均极限的显式结构和相关的平均场纳什确定性等价方程组。此外,还证明了分散最优策略满足近似纳什均衡性质。通过工程实例验证了所提理论结果的正确性。

Dynamic optimization problems for mean-field stochastic large-population systems
This paper considers dynamic optimization problems for a class of control average mean-field stochastic large-population systems. For each agent, the state system is governed by a linear mean-field stochastic differential equation (MF-SDE) with individual noise and common noise, and the weight coefficients in the cost functional can be indefinite. The decentralized optimal strategies are characterized by stochastic Hamiltonian system, which turns out to be an algebra equation and a mean-field forward-backward stochastic differential equation (MF-FBSDE). Applying the decoupling method, the feedback representation of decentralized optimal strategies is further obtained through two Riccati equations. The solvability of stochastic Hamiltonian system and Riccati equations under indefinite condition is also derived. The explicit structure of the control average limit and the related mean-field Nash certainty equivalence (NCE) equation systems are also discussed by some separation techniques. Moreover, the decentralized optimal strategies are proved to satisfy the approximate Nash equilibrium property. The good performance of the proposed theoretical results is illustrated by a practical example from the engineering field.
