中文摘要: 本项目重点研究网络化控制系统中以优化状态估计性能为目标的传感器调度问题。在网络化控制系统中,状态估计是控制器设计的基础,其精度依赖于传感器观测值的传输。而在实际应用中,传感器的通信往往受到限制(如有限能源、有限带宽等),不能实现充分的数据传输。针对这种情形,如何设计传感器的传输方案,即设计传感器的调度策略,使系统获得最优估计精度,是一个具有重要理论价值和现实意义的问题。本项目将深入研究几类不同模型中的传感器调度问题,探索系统中估计精度与调度策略之间的关系,对最优调度方案进行分析,提出高效的优化调度算法。并在理论分析的基础上,进一步搭建实际仿真平台进行实验,为理论在实际中的应用奠定基础。

英文摘要: This proposal considers the sensor scheduling problem for state estimation performance in networked control systems. In a networked control system, state estimation is fundamental to controller design and its performance depends on the measurements transmission from sensors. In practical applications, communication resource may be limited and the transmission is hence constrained. It is important to ask this question: how to schedule the sensor communication such that the state estimation quality is optimized. This proposal aims to answer it. It proposes various models and considers the corresponding sensor scheduling problems. It studies the connections between the estimation performances and the scheduling strategies, with the objective to analyze the optimal schedules and further provide algorithms to solve the problems. Moreover, simulations will be done in real applications for the further study.
