向上查表法在多功能传感器信号重构中的应用

Look-up Table Based Approach to Data Reconstruction in Multi-Functional Sensing

基于最小二乘法的基本原理和Moore-Penrose广义逆矩阵的基本性质,讨论了一种重构多功能传感器被测信号的方法——向上查表法(LUT)。该算法可以用来解决三元被测量的重构问题,并考虑了测量矩阵的数据病态可能性。为了证明算法的有效性,建立了多功能传感器模型电路并给出算法应用的理论推导、实验结果和重构误差分析。

It discusses a novel algorithm in signal reconstruction for multi-functional sensorsLook Up Table(LUT),which is based on least square method and the reverse function of Moore-Penrose Matrix. The proposed method is capable of measurand reconstruction of three variables, and is immune to morbidity of data matrix. In order to validate this arithmetic, emulation circuits are put forward together with the theories analysis, as well as the experiment results and error analysis.
