[0044] The present invention will be further explained below in conjunction with the drawings.
[0045] The present invention is aimed at the needs of aero engine performance estimation and health management, and expands and designs and develops the existing turbofan engine performance estimation method based on distributed filtering. Improve the extended Kalman filter algorithm, improve the estimation accuracy of the filter algorithm when there is data packet loss, establish an adaptive correction mechanism of the variance matching method, integrate all the nonlinear calculations of the algorithm and put them into the main filter to reduce The computational burden of the sub-filter is reduced.
[0046] Compared with the traditional distributed extended Kalman filter performance estimation algorithm, it solves the problem that the accuracy of the estimation result is reduced due to the sensor signal packet loss, and the component performance parameter estimation result has a large ...
