In order to improve its positioning and navigation accuracy, Kalman filtering algorithms are usually used to process navigation data. This paper combines fuzzy control theory with Kalman filter, and proposes an integrated navigation algorithm based on fuzzy control theory, specifically observing each component of the residual error, using multiple fuzzy inference systems to modify the measurement noise variance matrix to approximate the real noise characteristic. Through multiple simulation experiments, the results show that the algorithm can effectively suppress the filtering divergence.","PeriodicalId":337028,"journal":{"name":"The 8th International Symposium on Test Automation & Instrumentation (ISTAI 2020)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126110508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, the actual value and error of DC current ratio were available. Meanwhile, circuit diagrams, calibration process and examples were provided; measurement uncertainty was evaluated. The result shows that the proposed methods meet the calibration requirements of DC current ratio instruments; the expanded uncertainty for the 1 A: 1 A～ 1000 A: 0.5 A ratio is 1.7×10-8～8.4×10-6.
