Abstract

Сигнальное устройство сейсмического источника, предназначенное для генерирования сигнала сейсмического источника, может включать компонент сейсмического источника для связывания рабочего тела с почвой; управляемый клапан, функционально подключенный к компоненту сейсмического источника; и управляющее устройство, управляющее управляемым клапаном посредством первичного управляющего сигнала, генерируемого путем применения модели отклика управляемого клапана в выбранном рабочем диапазоне. Указанная модель применяется для уменьшения нелинейности в характеристике зависимости расхода от перемещения управляемого клапана.
