我们考虑了一组结构相同的LTI系统的初始状态的重建问题,在这种情况下,在组中的各个系统的输出测量是在离散的时间步长和匿名的方式接收:虽然我们知道所有的输出测量组中的各个系统,我们不知道哪个输出测量对应于哪个系统。这个特定的状态估计问题是由应用领域中正在出现的问题所激发的,所述应用领域处理结构相同的系统的群体,例如由于经济或技术原因,仅可能将群体作为一个整体来测量。我们采用了一种测量理论的方法,在该方法中,该集团是由一个LTI系统描述的结构的个人系统和一个初始状态,这是由一个离散的措施表示。我们得到的状态估计的特征,承认一个唯一的解决方案。
We consider the problem of reconstructing the initial states of a group of structurally identical LTI systems in the situation that output measurements of the individual systems in the group are received at discrete time steps and in an anonymized manner: While we do know all output measurements of the individual systems in the group, we do not know which output measurement corresponds to which system. This specific state estimation problem is motivated by emerging problems in applied fields that are dealing with populations of structurally identical systems for which it is only possible to measure the population as a whole, e.g. due to economic or technological reasons. We adopt a measure theoretical approach in which the group is modelled by an LTI system describing the structure of the individual systems and an initial state which is expressed by a discrete measure. We derive characterizations for the state estimation to admit a unique solution.
