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 ...

Error analysis of forced discrete mechanical systems
(American Institute of Mathematical Sciences, 2021-12)
The purpose of this paper is to perform an error analysis of the variational integrators of mechanical systems subject to external forcing. Es- sentially, we prove that when a discretization of contact order r of the La- ...
