An LMI Approach to Full- and Reduced-Order Switched Luenberger Observers for Switched Affine Systems
(2016-12-01)
This work deals with reduced-order Luenberger-like observer design and control for switched affine systems. Formulation of state-dependent and dynamic output-dependent switching laws for those systems was already addressed, ...
Fault detection in rotating machinery by using the modal state observer approach
(2019-10-13)
The existence of cracks in rotating shafts can lead to failures, which imply economic losses and security issues. In the last decades, attention has been devoted to this subject leading to the development of vibration-based ...
Design of a state observer using decay rate LMI constraints for fault detection in mechanical systems
(2010-01-01)
Nowadays, one of the most important concerns for many companies is to maintain the operation of their systems without sudden equipment break down. Because of this, new techniques for fault detection and location in mechanical ...
Mixed order fractional observers for minimal realizations of linear time-invariant systems
(2018)
Adaptive and non-adaptive minimal realization (MR) fractional order observers (F00) for linear time-invariant systems (LTIS) of a possibly different derivation order (mixed order observers, MOO) are studied in this paper. ...
Analise de desempenho de observadores de estado robustos na localizacao de falhas
(2000-12-01)
The state observers can reconstruct and monitor unmeasurable states. A new concept of fault detection and isolation using state observers is presented. The method selects the parameters from components that may fail during ...
A Recursive Algorithm for Set-Valued Observers with Dynamic Uncertainties
(Planta Piloto de Ingeniería Química, 2000-12)
In this work we present a new algorithm for set-valued state propagation in observers with dynamic uncertainties. In comparison with recently results published in the specialized literature, the novel approach presents the ...
