本文研究了分布式传感器网络中系统状态与部分未知动力学的联合估计问题,特别是在仅有部分状态观测可用的场景下。为解决该问题,我们提出了一种基于观测器的动态协作学习框架,该框架结合了在线分布式高斯过程(GP)回归,能够在测量不完整且GP模型不完善的情况下实现准确估计。此外,我们引入了一种新颖的数据收集策略,并提供了确保数据采集可行性的理论条件。同时,我们还利用GP的确定性误差界,推导了涵盖状态估计和模型估计的误差上界。实证模拟表明,与现有基于分布式GP的方法相比,我们的方法具有优越性。
英文摘要
In this paper, we tackle the problem of jointly estimating the system states and partially unknown dynamics within distributed sensor-equipped networks, particularly in scenarios where only partial state observations are available. To address this issue, we propose an observer-based dynamic cooperative learning framework incorporating online distributed Gaussian Process (GP) regression, which enables accurate estimation despite incomplete in measurements and deficient GP models. In addition, a novel data collection strategy is introduced, with theoretical conditions ensuring feasible data acquisition. Moreover, we also derive an error upper bound encompassing state estimation and model estimation, leveraging the deterministic error bounds of GPs. Empirical simulations demonstrate the superiority of our approach compared to existing distributed GP-based methods.
