2019年12月2日上午，香港城市大学Gang Feng教授与香港科技大学Ling Shi副教授应邀在将军路校区自动化学院4号楼507会议室分别做了题为“Optimal converge control of heterogeneous mobile sensor networks”与“Sensor Scheduling for Remote State Estimation with Unknown Communication Channel Statistics: A Learning-based Approach”的学术报告。报告由南京航空航天大学自动化学院院长江驹教授主持，自动化学院副院长陈谋教授及部分师生参加了学术报告会。

Feng教授首先以环境监视与信息侦查为应用背景，引出了异构多传感器网络的收敛问题，并指出了多传感器收敛过程中的研究难点。接着，Feng教授介绍了异构传感器网络的数学模型框架，提出了一种收敛性能指标函数，并对性能指标函数进行了分析。然后，Feng教授给出了基于固定通信拓扑和收敛通信范围的收敛目标，并提出了对应的收敛控制律，同时对收敛性进行了分析。通过一组仿真结果，Feng教授对所提出的方法进行了验证，展示了他们团队的最新研究成果。最后，Feng教授对汇报内容进行了总结，并对如何将异构传感器网络扩展至多维空间等研究方向提出了展望。

随后，Shi教授向在场师生分享了他在最优状态估计方面的最新研究成果。他首先以智能制造与环境监测为例，介绍了无线传感器网络最优状态估计问题的研究意义。接着，他通过结合传统卡尔曼滤波器与伯努利丢包模型，引出了最优状态估计的核心问题。然后，Shi教授详细讲解了已知信道条件与未知信道条件下的调度问题，提出了用于最优估计策略的阈值结构与异步学习算法，并通过仿真验证展示了该方法的有效性。最后，Shi教授对多传感器信息融合的最优状态估计等研究方向进行了展望。

报告结束后，Feng教授和Shi教授与参会师生针对报告内容进行了热烈的讨论，对师生们提出的问题给予了详细的解答，并与部分师生合影留念。
