基于蒙特卡洛法的直流电子负载恒定电阻测量结果不确定度评定

The Uncertainty Evaluation of Measurement Results of Constant Resistance of DC Electronic Load Based on Monte Carlo Method

本文采用蒙特卡洛法(MCM法)对直流电子负载的电阻功能进行不确定度评定,应用MCM Alchimia软件可提高MCM法的计算速度。并与GUM法进行比较,进而得出在相同模型的条件下应用MATLAB对蒙特卡洛法的不确定度评定结果更为可靠。最终通过MATLAB对MCM Alchimia软件进行验证。

In this paper,Monte Carlo method(MCM method)is used to evaluate the uncertainty of the resistance function of DC electronic load.The application of MCM Alchimia software can improve the calculation speed of MCM method.Compared with the GUM method,the uncertainty evaluation results of Monte Carlo method are more reliable when MATLAB is applied under the same model.Finally,the MCM Alchimia software was verified by MATLAB.
