Functional Detectability and Asymptotic Functional Observer Design
IEEE Transactions on Automatic Control, 2023The objective of this paper is to present a new solution to the functional observer design problem. First, a new definition for functional detectability is given, then some algebraic conditions for linear multivariable systems to be functional detectable are presented.

On functional observability and functional observer design
AutomaticaThis manuscript deals with the problem of observer design, to estimate all the states of a system. Let us consider the following multivariable system, \begin{align*} \dot{x}(t) & = A x(t)+B u(t),\\ y(t) & = C x(t),\\ z(t) & = L x(t), \end{align*} with the initial state \(x(0)=x_0\), \(x(t) \in \mathbb{R}^n\) is the state vector, \(u(t) \in \mathbb{R}^m\

Generality of functional observer structures
IEEE Conference on Decision and Control and European Control Conference, 2011 Functional observers estimate a linear function of the state vector directly without having to estimate all the individual states. In the past various observer structures have been employed to design such functional estimates. In this paper we discuss the generality of those various observer structures and prove the conditions under which those ...

On the Existence and Design of Functional Observers
IEEE Transactions on Automatic Control, 2020This paper concerns the problem of designing a functional observer. It gives a general presentation and a new formulation for the design of the observers considered by Darouach [1] in 2000. By introducing the controllability and stabilizability notions, the necessary and sufficient conditions for the existence of these observers are revised and proved,

On the Functional Observer Design With Sampled Measurement
IEEE Transactions on Automatic Control, 2023In this paper, a functional observer for continuous systems with sampled measurement is designed for a class of nonlinear systems, operating under unknown inputs, and the existence conditions are derived. The nonlinear function, as a function of full states, is decomposed to Lipschitz term and an unknown one.

Nonlinear observer design techniques with observability functions
52nd IEEE Conference on Decision and Control, 2013Two different observer design techniques for linear and nonlinear systems based on the so-called observability function, which is related to the Gramian matrix in the linear case, are proposed. Asymptotic and finite-time convergence results are provided. The effectiveness of the proposed approaches are demonstrated via numerical simulations.

Sliding mode functional observers
2008 10th International Conference on Control, Automation, Robotics and Vision, 2008In this paper the concept of sliding mode is introduced in the design of functional observers. Conditions for the existence of the observer are given. How to design the observer parameters are also shown. Under special circumstances the sliding mode functional observer proposed in this paper reduces to the Utkin state observer.
