Title (DE) VERFAHREN UND VORRICHTUNG ZUM BESTIMMEN VON VERÄNDERUNGEN IM LÄNGSDYNAMISCHEN VERHALTEN EINES SCHIENENFAHRZEUGS
(EN) METHOD AND APPARATUS FOR DETERMINING CHANGES IN THE LONGITUDINAL DYNAMIC BEHAVIOUR OF A RAIL VEHICLE
(FR) PROCÉDÉ ET DISPOSITIF POUR DÉTERMINER DES MODIFICATIONS DANS LE COMPORTEMENT DE DYNAMIQUE LONGITUDINALE D'UN VÉHICULE FERROVIAIRE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zum Bestimmen von Veränderungen im längsdynamischen Verhalten, insbesondere eines Fahrwerks, eines Schienenfahrzeugs zur Identifikation eines aktuellen Fahrzustandes des Schienenfahrzeugs, bei dem mittels eines regelungstechnischen Beobachters (1) aus einem bekannten oder messtechnisch ermittelten Eingangssignal (u) und zumindest einem Messsignal (y) des beobachteten Schienenfahrzeugs als beobachtetes reales Referenzsystem (10) durch ein Systemmodell (20) des Schienenfahrzeugs nicht messbare und das längsdynamische Verhalten charakterisierende Größen rekonstruiert und ausgewertet werden. Das zumindest eine Messsignal (y) des beobachteten Schienenfahrzeugs (10) und ein entsprechendes rekonstruiertes Messsignal (ŷ) des Systemmodells (20) werden verglichen und die mittels Vergleich ermittelte Abweichung wird mit einem Regler rekursiv nachgeführt, so dass die ermittelte Abweichung minimiert wird.
(EN) The invention relates to a method for determining changes in the longitudinal dynamic behaviour, in particular of a chassis, of a rail vehicle for identification of a current driving state of the rail vehicle, in which, by means of a monitor (1) using control technology, quantities which are not measurable by a system model (20) of the rail vehicle and which characterise the longitudinal dynamic behaviour are reconstructed and evaluated as a monitored real reference system (10) from a known or metrologically determined input signal (u) and at least one measurement signal (y) from the monitored rail vehicle. The at least one measurement signal (y) of the monitored rail vehicle and a corresponding reconstructed measurement signal (ŷ) of the system model (20) are compared and the deviation determined by means of comparison is tracked recursively by a controller, such that the determined deviation is minimised.
(FR) L'invention concerne un procédé pour déterminer des modifications dans le comportement de dynamique longitudinale, en particulier d'un bogie, d'un véhicule ferroviaire aux fins d'identification d'un état actuel de conduite du véhicule ferroviaire. Selon ledit procédé, des grandeurs ne pouvant être mesurées par un modèle de système (20) du véhicule ferroviaire et caractérisant le comportement de dynamique longitudinale sont reconstruites et évaluées au moyen d'un observateur relevant de la technique de régulation (1) à partir d'un signal d'entrée (u) connu ou déterminé par des techniques de mesure et d'au moins un signal de mesure (y) du véhicule ferroviaire surveillé en tant que système de référence réel (10) observé. Le signal ou les signaux de mesure (y) du véhicule ferroviaire (10) observé et un signal de mesure reconstruit (ŷ) correspondant du modèle de système (20) sont comparés et l'écart déterminé au moyen d'une comparaison est ajusté de manière récursive à l'aide d'un régulateur, de telle sorte que l'écart déterminé est réduit au minimum.
