本文主要研究了性能退化条件下评估传感器可靠性时,退化模型选择的问题。首先简述了TOPSIS法的概念与原理,给出了该方法的实现步骤。然后研究了利用TOPSIS法选择传感器性能退化模型的方法,并利用MATLAB语言编程实现了该算法。最后,以某型号霍尔电流传感器为研究对象,利用TOPSIS法对其进行了性能退化模型的选择。经检验,该方法选择的模型与企业返回的经验数据基本相符。
In this paper, we mainly study the problem of degradation model selection when evaluating sensor reliability under performance degradation. Firstly, the concept and principle of TOPSIS method are briefly described, and the steps of realization of this method are given. Then the method of selecting sensor degradation model by TOPSIS is studied and the algorithm is programmed by using MATLAB language. Finally, taking a model Hall current sensor as the research object, the TOPSIS method is used to select the performance degradation model. After testing, the method selected model and the empirical data returned by business basically match.
