基于模糊系统的接触电阻建模方法
Modeling Method of Contact Resistance Based on Fuzzy System
摘要
Abstract
The contact resistance is important for dependability of electrical contact.We put forward a modeling method based on fuzzy system isfor contact resistance.Training data and testing data are obtained from the experiment.The improved algorithm is developed by combining basic ant colony algorithm and recursive least square algorithm.The parameters of fuzzy system are obtained through the training data,and the training algorithms are the recursive least square algorithm,basic ant colony algorithm,and improved algorithm,respectively.Compared with that of other two algorithms,the convergence error of the improved algorithm decreases more than one time.The model of contact resistance based on regression analysis is also built.Every model is tested by testing data.The dependability of model is verified and the prediction result is compared.Compared with that of other two models,the prediction error of fuzzy system trained by improved algorithm decreases 10％.The results of prediction and comparison show that the fuzzy system trained by improved algorithm is reliable to model contact resistance.关键词
