For the first time, a very important universal rule is presented. I.e. the sufficient and necessary condition of optimal phase margin to be 60 degree is that, the optimum modulus theory must be satisfied. The significance of this conclusion can be reflected by two aspects: one is help to choose the optimal parameters for expected characteristic, and the other is to be the optimal phase compensation criterion for system correction. According to the rule above, an optimal parameters of one-dimensional fractional system is given which correct the error of traditional typical I and typical II system engineering design methods.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"120 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126282052","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 is necessary to locate the corrosion from the ground after the detection is completed. The four-step comprehensive method, which contains course wheel orientation, welding lines modification, outer orientation modification and revolving angle orientation, is proposed in this paper. At the same time, outer orientation modification usually use the way of low-frequency electromagnetic wave to modify the course wheel's count, for improving the precision. This article establishes the outer orientation model, deduces the formula of the magnetic strength in the pipeline, and uses ANSYS software to simulate the model. The simulation not only accords with the experiment, but also shows that different parameters would affect the magnetic strength in the pipeline. It is significant to understand the outer orientation technology with low-frequency electromagnetic waves.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121977648","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}
