多传感器自适应加权数据融合在测量排气温度的应用

航空发动机的试车过程在强干扰环境条件下进行,为了准确测量排气温度T4,本文介绍了一种多个同类传感器数据的自适应加权融合方法,并将此方法应用到发动机试车过程排气温度T4的测量中,经过对试车过程的排气温度T4测量结果进行分析,证明此方法对减少测量误差有很明显的效果,能有效地在试车测量过程中应用.

Multi-sensor self-adaptive weight added fusion method applied in testing exhaust temperature

The aircraft engine trial run process carries on under heavy interferential condition,in order to accurately surveys the discharge temperature T4,this article introduced Multi-sensor self-adaptive weight added fusion method,and applies this method in testing discharge temperature T4,passes through carries on the analysis to the trial run process discharge temperature T4 measurement result,proved this method to reduces the measuring error to have the very tangible effect,can effectively apply in the trial run survey process.
