A Hybrid Observer for Estimating the State of a Distributed Linear System

Lili Wang, Ji Liu, A. Stephen Morse

A hybrid observer is described for estimating the state of a system of the form dot x=Ax, y_i=C_ix, i=1,...,m. The system's state x is simultaneously estimated by m agents assuming…

Lyapunov Approach to Consensus Problems

Angelia Nedich, Ji Liu

This paper investigates the weighted-averaging dynamic for unconstrained and constrained consensus problems. Through the use of a suitably defined adjoint dynamic, quadratic Lyapun…
