离散时间平均场随机$H_2/H_\infty$控制

Discrete-time Mean-field Stochastic $H_2/H_\infty$ Control

Zhang Weihai, Ma Limin

摘要:

研究了离散时间系统的平均场型有限时域$H_2/H_\infty$控制问题。首先,我们得到了一个平均场随机有界实引理(SBRL)。其次,给出了离散时间平均场随机线性二次(LQ)最优控制可解的一个充分条件。第三,在SBRL和LQ结果的基础上,利用耦合矩阵值方程的可解性,建立了平均场型离散时间随机$H_2/H_\infty$控制存在的充分条件。

英文摘要:

The finite horizon $H_2/H_\infty$ control problem of mean-field type for discrete-time systems is considered in this paper. Firstly, we derive a mean-field stochastic bounded real lemma (SBRL). Secondly, a sufficient condition for the solvability of discrete-time mean-field stochastic linear-quadratic (LQ) optimal control is presented. Thirdly, based on SBRL and LQ results, this paper establishes a sufficient condition for the existence of discrete-time stochastic $H_2/H_\infty$ control of mean-field type via the solvability of coupled matrix-valued equations.
