Distributed Observer for Systems Driven by Exogenous Signals

This paper proposes a distributed observer for linear time-invariant systems driven by a class of exogenous input signals within the multi-agent consensus framework. Such an exogenous input is assumed to be generated by an exosystem, and so is expected to be reconstructed from the output. To construct the distributed observer, a group of sensor nodes are deployed to measure the output of the system. With limited output information acquired, a single node may not be able to reconstruct the full state of the system as well as the exogenous input signal. Thus, a protocol of neighboring-feedback cooperation is designed so that each node can achieve the reconstruction objective without fail.
