Abstract

Описаны способ, система и устройство для обновления моделей коллектора в реальном времени с помощью множественных фильтров Калмана. Способ включает в себя этап согласования для приведения статических и динамических переменных состояния в соответствии друг с другом в ходе временного этапа обновления. Кроме того, используется способ итеративного демпфирования совместно с этапом согласования, чтобы учитывать негауссовские и нелинейные признаки в системе. Также описан способ повторной дискретизации, который уменьшает размер совокупности моделей коллектора, которые должны быть обновлены.
