Abstract :
In this paper, we present two approximate filtering algorithms for estimating states of a distributed networked control system (DNCS). A DNCS consists of multiple agents communicating over a lossy communication channel, e.g., wireless channel. While the time complexity of the exact method can be exponential in the number of communication links, the time complexity of an approximate method is not dependent on the number of communication links. In addition, we discuss the general conditions for stable state estimation of DNCSs.
