| 摘要 |
An engine tracking filter system that obtains information from two or more operating conditions to estimate health parameters P, performance parameters Yp, and sensor estimates Ys, is described. Such multipoint estimation of engine health enables estimation of all engine health parameters rather than only a few engine health parameters for use in engine component diagnostics, trending, and fault detection and isolation. In addition, such estimation is believed to provide improved estimates of sensed parameters for use in sensor redundancy management and sensor elimination, and also is believed to provide improved estimates of performance parameters for use in model based control to reduce required temperature, stall, and other margins.
