| Zusammenfassung: | A method for approximating compressible flow is described that is applicable across any pressure range of interest uses upstream and downstream pressure. The approximation minimizes variance with respect to a true flow equation. A flow control system is given using the new method that achieves accurate control with minimum complexities. The control system is application to various systems, including internal combustion engine airflow control, internal combustion engine exhaust gas recirculation control, internal combustion engine alternative fuel flow control, and many other compressible flow control problems. |
