Abstract | Systems and methods for estimating an engine event location are disclosed herein. In one embodiment, a controller is configured to receive a signal from at least one knock sensor coupled to a reciprocating engine, transform the signal, using a multivariate transformation algorithm, into a power spectral density, transform the power spectral density into a plurality of feature vectors using predictive frequency bands, predict the engine event location using at least the plurality of feature vectors and a predictive model, and adjust operation of the reciprocating engine based on the engine event location.
Il est décrit des systèmes et des procédés permettant destimer lemplacement dun événement moteur. Dans un mode de réalisation, un contrôleur est configuré pour : recevoir un signal dau moins un capteur de détonation couplé à un moteur alternatif; transformer le signal, au moyen dun algorithme de transformation multivariable, en une densité spectrale de puissance; transformer la densité spectrale de puissance en une pluralité de vecteurs dattributs au moyen de bandes de fréquences prédictives; prédire lemplacement de lévénement moteur en utilisant au moins la pluralité de vecteurs dattributs et un modèle de prévision; et régler le fonctionnement du moteur alternatif daprès au moins lemplacement de lévénement moteur. |
