最小二乘优化模糊系统的接触电阻计算方法

The Method for Calculating the Contact Resistance Used Fuzzy System Optimized by Recursive Least Square

根据接触电阻的特点,运用模糊系统对其进行计算。设计试验得到训练数据与测试数据,通过训练数据训练模糊系统,建立相应模型,训练算法为递推最小二乘结合禁忌搜索算法。通过回归分析建立相应模型。通过测试数据测试所建立的两种模型,并比较,接触电阻的模糊系统模型的测试结果优于回归分析,比较结果表明模糊系统适用于接触电阻的计算。

The contact resistance is modeled by fuzzy system for the characteristics.The experiment is designed and training data and testing data is got.Using training data,fuzzy system is trained,the model of contact resistance is set up,and training algorithm is recursive least square combined tabu search.The model of contact resistance is built through regression analysis.The two models are tested by testing data,the result is compared,and the model based on fuzzy system is better.The result shows that fuzzy system is suitable for calculating contact resistance.
