Practical Design Considerations For Signal Conditioning Unit Interfaced With Multi-Point Snow Temperature Recording System, Raman K. Attri, B. K. Sharma, M. A. Shamshi

Raman K. Attri

Multi-point Temperature Measurement has always been very important aspect of physical instrumentation mainly in environmental and Industrial application. A multi-point temperature measurement system has been developed to measure temperature at different points simultaneously. This multi-channel system is designed specifically for measuring snow temperature at 28 different points in snow layers and this multi-point data is used in modeling of snow cover. The interfacing of such multi-channel system to Data acquisition system is one of the most critical design aspects, which affect the overall performance of the system. The temperature sensor system and Data Acquisition System may be working satisfactorily when …


Commande Vectorielle Indirecte D'Un Moteur À Induction Par Logique Floue, Boukhemis Chetate , Aissa Kheldoun Dec 1999

Commande Vectorielle Indirecte D'Un Moteur À Induction Par Logique Floue, Boukhemis Chetate , Aissa Kheldoun

La commande vectorielle indirecte est actuellement la technique la plus utilisée pour contrôler la vitesse (ou la position) des actionneurs électriques à courant alternatif. Malheureusement les paramètres de la machine changent en raison de l'échauffement de ses parties ou à cause de l'interaction avec le mécanisme entraîné. Le présent travail, est consacré à l'application de la logique floue, d'une part, pour régler et adapter la constante de temps rotorique du moteur découplé par la technique à champ orienté et, d'autre part, en vue d'améliorer les performances correspondantes en cas de changement du moment d'inertie et d'application de la charge.
