摘要：对于多自主体系统，分布式反馈优化研究各个自主体如何利用其自身状态及局部梯度信息的实时反馈值以及自主体之间的实时信息交换使整个多自主体系统的状态趋近于某个总体优化指标的最优值点。分布式反馈优化必须同时克服多自主体系统自身复杂动力学和分布式信息获取所带来的挑战。本报告研究当多自主体系统包含不确定非线性动力学时，如何充分利用非线性系统的鲁棒和自适应控制手段来解决分布式反馈优化问题。

摘要：This talk is to introduce the framework of stochastic extremum seeking (ES) method and its applications. Firstly, we introduce a theoretical analysis tool for stochastic ES, namely, stochastic averaging theory for general local Lipschitz nonlinear systems with stochastic disturbance. Then, we present stochastics ES algorithms for static maps and dynamical nonlinear systems. Finally, we give some applications of stochastic ES to source seeking and optimal control.

报告摘要：This paper investigates open-loop and feedback solutions of linear quadratic mean field games with a leader and a large number of followers. The leader first gives its strategy and then all the followers cooperate to optimize the social cost as the sum of their costs. By variational analysis with mean field approximations, we obtain a set of (strict) open-loop controls of players in terms of solutions to mean field FBSDEs, which is further shown be to an asymptotic Stackelberg equilibrium. By applying the matrix maximum principle, a set of decentralized feedback strategies is constructed for all the players. For open-loop and feedback solutions, the corresponding optimal costs of all players are explicitly given by virtue of the solutions to two Riccati equations, respectively.
