摘要：
Pneumatic state estimation operations for estimating gas flow and pressure at pneumatic nodes and flow branches within a reticulated engine system for engine control and diagnostic operations resolves net flow imbalances at specific pneumatic nodes and attributes such imbalances to inaccuracies in pneumatic state estimation. Inaccuracies are corrected as a function of a prior pneumatic state estimate and of a net flow imbalance at the node or a neighboring node for precision engine control and diagnostic operations.
