TLDR
A new finite-time convergent functional dynamical observer design for descriptor systems that is applied to the sensor and actuator faults detection and estimation and used in the observer-based fault tolerant control design.Abstract:
In this paper a new finite-time convergent functional dynamical observer design for descriptor systems is presented. The conditions for its existence and stability are given. This observer is then applied to the sensor and actuator faults detection and estimation. This estimation is used in the observer-based fault tolerant control design. All the obtained results are illustrated by numerical examples.read more

A sliding mode observer for robust fault reconstruction in a class of nonlinear non-infinitely observable descriptor systems
TL;DR: A sliding mode observer (SMO) for robustly reconstructing faults affecting a class of nonlinear non-infinitely observable descriptor systems and preliminary transformations are utilised to re-express the system such that the design freedom in its structure is easier to exploit.

On the observer design for descriptor systems
P.C. Muller,M. Hou +1 more
TL;DR: It is shown that impulse observability is not necessary for the existence of conventional observers for descriptor systems and under less restrictive conditions, a simple observer design approach is proposed.

Design of stabilizing controller for uncertain nonlinear systems under input saturation
TL;DR: A new method for modeling the saturation effect is presented that allows taking its nonlinearity effects into the problem of controller design and is a modified parallel distributed compensation state feedback.

Characteristics of LTI descriptor systems
TL;DR: In this article, rank conditions of suitable matrices composed of E, A, B without applying the equivalence transformation are derived for linear time-invariant descriptor systems. But the authors do not deal with the related characteristics of these matrices.
