Distributed Observers for LTI Systems with Finite Convergence Time: A Parameter Estimation-based Approach
A novel approach to solve the problem of distributed state estimation of linear time-invariant systems is proposed in this paper. It relies on the application of parameter estimation-based observers, where the state observation task is reformulated as a parameter estimation problem. In contrast with existing results our solution achieves convergence in finite-time, without injection of high gain, and imposes very weak assumptions on the communication graph---namely the existence of a Hamiltonian walk. The scheme is shown to be robust vis-\'a-vis external disturbances and communication delays.

Symmetry-based observers for ODE systems
In this paper we introduce an observer design framework for ordinary differential equation (ODE) systems based on various types of existing or even novel one-parameter symmetries (exact, asymptotic and variational) endin…
Distributed Prescribed-Time Observer for Nonlinear Systems in Block-Triangular Form
This paper proposes a distributed prescribed-time observer for nonlinear systems representable in a block-triangular observable canonical form. Using a weighted average of neighbor estimates exchanged over a strongly con…

Infinite-dimensional observers for high order boundary-controlled port-Hamiltonian systems
This letter investigates the design of a class of infinite-dimensional observers for one dimensional (1D) boundary controlled port-Hamiltonian systems (BC-PHS) defined by differential operators of order $N \geq 1$. The c…
Communication-aware Multi-agent Systems Control Based on $k$-hop Distributed Observers
We propose a distributed control strategy to allow the control of a multi-agent system requiring k-hop interactions based on the design of distributed state and input observers. In particular, we design for each agent a …
