The goal of this paper consists in applying pattern recognition methods to turbo-generators. Previous works have shown that a monitor, thanks to pattern recognition, is practical on asynchronous machines. This procedure has rarely taken advantage of these methods for turbogenerator. The statistical model has been obtained from harmonics extracted from flux probes and from stator current and voltage...
Among failures that are observed in power plants, rotor faults have often been recorded. Thus, radial flux probes have been introduced in most generators to anticipate heavy rotor faults such as rotor ground faults. However, the commonly used signal processing done with those rotor flux measurements makes the diagnosis complicated. The aim of this paper is to present a diagnosis method based on statistical...
Ultrasonic transducers can be used to control friction. In case of a haptic texture actuated and explored simultaneously with the bare finger, this technology allows to reduce perceived roughness. In this article, we investigate its use to understand determinants of friction at contact. In the literature, a researcher recently suggested that microtexture perception was mainly determined by an interaction...
