论文摘要
本文从分布式优化观点研究了分布式的卡尔曼过滤(DKF)。由于Kalman过滤是最大的后验估计(MAP)问题,这是一个二次优化问题,我们将DKF问题重新制定为共识优化问题,从而将其通过许多现有的分布式优化算法来解决。提出了一种采用双重上升方法的新的DKF算法,并在轻度假设下证明了其稳定性。通过数值实验评估所提出的算法的性能。
This paper investigates the distributed Kalman filtering (DKF) from distributed optimization viewpoint. Motivated by the fact that Kalman filtering is a maximum a posteriori estimation (MAP) problem, which is a quadratic optimization problem, we reformulate DKF problem as a consensus optimization problem, resulting in that it can be solved by many existing distributed optimization algorithms. A new DKF algorithm employing the dual ascent method is proposed, and its stability is proved under mild assumptions. The performance of the proposed algorithm is evaluated through numerical experiments.
