Design of a distributed finite-time observer

Participants : Denis Efimov, Rosane Ushirobira.

In [46], a distributed observer was presented to estimate the state of a linear time-invariant plant in finite-time in each observer node. The design was based on a decomposition into locally observable and unobservable substates and on properties of homogeneous systems. Each observer node can reconstruct in finite-time its locally observable substate with its measurements only. Then exploiting the coupling, a finite-time converging observer was constructed for the remaining states by adding the consensus terms.
