摘要 根据接触电阻的特点,运用基于模糊系统的方法计算接触电阻。利用递推最小二乘算法训练模糊系统建立了接触电阻模型,并利用训练数据建立了接触电阻的回归分析模型。通过区别于训练数据的测试数据对所建立的两种模型进行测试,对其可靠性进行检测,并对其进行了比较分析。结果表明:基于模糊系统的接触电阻模型的测试结果优于回归分析,且基于模糊系统的方法在接触电阻的计算方面具有优势。 According to the characteristics of contact resistance,a new method of modeling contact resistance based on fuzzy system optimized by recursive least square algorithm is put forward.A model of contact resistance is set up by using training data obtained from experiment.The regression analysis model of contact resistance is built through training data.The two models are tested by testing data that is different from training data and the results are compared.The test outcome of the model based on fuzzy system is better than that of regression analysis.The result of test and comparison shows that the fuzzy system optimized by recursive least square algorithm has advantage in modeling contact resistance.
