A Scalable Modularized Synthesis Method for Distributed Kalman Filters
(2011) 18th IFAC World Congress, 2011- Abstract
- This paper presents a scheme to construct distributed observers for a system consisting of agents interconnected in a graph structure. The scheme is an iterative procedure to improve the observers with respect to global performance. It is modular in the sense that each agent iterates using only local model information. As a consequence, the complexity of the scheme scales linearly with the size of the system. The resulting observers estimate states for each agent using only local measurements and model knowledge of its neighbors. Distributed observers are suboptimal to centralized ones and it is desirable to measure the amount of performance degradation. We show how to use the variables of the synthesis scheme to also determine such a... (More)
