论文摘要
本文提出了一种解决线性时间不变系统的分布式状态估计问题的新方法。它依赖于基于参数估计的观察者的应用,在该观察者中,状态观察任务被重新重新构成参数估计问题。与现有结果相反,我们的解决方案在有限的时间内实现了融合,而无需注入高增益,并且在通信图上施加了非常弱的假设,即存在哈密顿步行。该方案被证明是强大的相对于外部干扰和沟通延迟。
A novel approach to solve the problem of distributed state estimation of linear time-invariant systems is proposed in this paper. It relies on the application of parameter estimation-based observers, where the state observation task is reformulated as a parameter estimation problem. In contrast with existing results our solution achieves convergence in finite-time, without injection of high gain, and imposes very weak assumptions on the communication graph---namely the existence of a Hamiltonian walk. The scheme is shown to be robust vis-á-vis external disturbances and communication delays.
