By combining feedback correction approach, the observer states can close to system states as exactly as possible, and chattering is eliminate simultaneously. Because of the employing of receding horizon optimization technique, the observer compensatory term can be optimized continuously and on-line. The proposed method guarantees the SMO is robustly stable. The satisfying properties of the SMO are verified by a numerical example.","PeriodicalId":375613,"journal":{"name":"2008 IEEE International Symposium on Knowledge Acquisition and Modeling Workshop","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114456291","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}

It was brought forward a comprehensive scheme for position error correction. The experiment platform was based on Superstar II GPS receiver and Matlab. It mainly corrected the position error such as satellite clock error, ionospheric error, tropospheric error, the earth rotation effect etc. Moreover, ionospheric delay error was corrected for about 14 m by Klobuchar model; tropospheric error was corrected for the average value of 4.05 m by the altitude angle module and so on. Especially, the satellite clock error was corrected for 3.1 m related to IGS by empirical formula. The user clock error is the max error with magnitude of 104~105 s to affect position result. Finally, these methods improved the positioning precision to 17 m. The result of experiment has proved the validity of these correcting methods, accumulating much experience for the next investigation.","PeriodicalId":375613,"journal":{"name":"2008 IEEE International Symposium on Knowledge Acquisition and Modeling Workshop","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122727151","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}
