Adaptive Set Observers Design for Nonlinear Continuous-Time Systems: Application to Fault Detection and Diagnosis
Adaptive observers nonlinear continuous-time systems fault detection interval residuals
2010/12/28
The paper deals with joint state and parameter estimation for nonlinear continuous-time systems. Based on a guaranteed LPV approximation, the set adaptive observers design problem is solved avoiding t...

The cosmological backreaction: gauge (in)dependence, observers and scalars
The cosmological backreaction gauge (in)dependence observers
2010/12/27
We discuss several issues related to a recent proposal for defining classical spatial averages to be used in the so-called cosmological backreaction problem. In the large averaging-volume limit all ga...

Boundary stress tensors for spherically symmetric conformal Rindler observers
surface energy conformal Rindler geometry horizon en-tropy equipartition law
2010/3/22
The boundary energy - momentum tensors for a static observer in the conformally flat Rindler geometry are considered. We found the surface energy is positive far form the Planck world but the transver...
A useful guide for gravitational wave observers to test modified gravity models
gravitational wave modified gravity models
2010/3/17
We present an extension of a previously suggested test of all modified theories of gravity that would reproduce MOND at low accelerations. In a class of models, called "dark matter emulators", gravita...
DESIGN OF NONLINEAR OBSERVERS
2007/8/7
The design of observers for nonlinear controlled systems presented in this paperconsists of two stages. In the first stage, the nonlinear controlled system is transformed intoan observability canonica...
