Summary:In this paper, a distributed adaptive observer scheme is designed for state reconstruction of linear time-invariant (LTI) systems with unknown dynamics. Specifically, a set of sensor nodes are deployed to distributedly measure the system state information, to restore the state and dynamics within it. Due to limitation of measurement capacity, individual node may not be able to measure the entire state. By achieving consensus with neighbors through a communication network, each node can adaptively reconstruct the system dynamics and estimate the system state asymptotically. The design of distributed adaptive observers for LTI systems with no input and with bounded unknown input are discussed, respectively. The completely distributed design in this paper requires no global information such as communication topology, collective measurement channel, or bound of the components of the system dynamics.
