HANDLING DISCARDABLE MEASUREMENTS IN POWER-SYSTEM STATE ESTIMATION
(Ieee-inst Electrical Electronics Engineers IncNew York, 1992)
On the use of Gram matrix in observability analysis
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
This letter presents some notes on the use of the Gram matrix in observability analysis. This matrix is constructed considering the rows of the measurement Jacobian matrix as vectors, and it can be employed in observability ...
Power System Observability Analysis Based on Gram Matrix and Minimum Norm Solution

Sequences Detection of an Unbalanced Sinusoidal Voltage of Unknown Frequency Using a Reduced-Order Observer
(Institute Of Electrical And Electronics Engineers, 2013-07)
This paper presents a globally convergent nonlinear observer capable of recovering the positive and negative sequences of an unbalanced grid voltage. The proposed algorithm has frequency adaptation, and is therefore, in ...
Observer-based control design for switched affine systems and applications to DC-DC converters
(2013-08-01)
This paper deals with the problem of establishing a state estimator for switched affine systems. For that matter, a modification on the Luenberger observer is proposed, the switched Luenberger observer, whose idea is to ...
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 ...
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 ...
