基于传感器数据融合的航空发动机电子控制器

Engine electronic controller based on sensor data fusion

提出了一种基于矩阵奇异分解法的传感器数据融合方法及其在某型航空发动机电子控制器设计上的应用。试验结果表明:该传感器数据融合算法简单有效,分别消除了发动机中进口空气温度T1传感器近7.8℃和涡轮后燃气温度T4传感器近19.2℃的测量误差,提高了发动机电子控制器工作的可靠性,并适应于未来航空发动机分布式控制的发展方向。

A sensor data fusion algorithm based on matrix singularity analysis and its application in a certain engine electronic controller （EEC） design are proposed. Experimental result demonstrates that this sensor data fusion arithmetic not only is simple and efficient ,but also can eliminate measuring error about 7.8℃ for T1 sensor and about 19.2℃ for T4 sensor. So it can improve the reliability of EEC and be applied to aero-engine distributed control system in future.
