By introducing the interference, time-delay and uncertain parameters to improve the nonlinear model, the objective of the work described here was to attenuate any various interference, time-delay and uncertain parameters factors in the actual network running environment. Using proper coordinate transformation, evaluation signal, energy storage function and adjusting appropriate weights, the systems satisfy the nonlinear L2 gain performance index. The robust controller achieves the desired queue size and guarantee asymptotic stability. This way ameliorates the instability phenomena, when the parameters of system were changed and subjected to the external interference. Finally, the simulation results confirm the feasibility and effectiveness of the designed scheme.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125923370","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}

However, most students cannot get circularly polarized light in the experiment. Two possible causes of this phenomenon are analyzed, thus, the thickness error of the quarter wave plate and the incident angle not being 0 degree at the plate surface. By comparing the theoretical and experimental results, we conclude that the main error comes from the thickness error of the plate. By investigating the cases of normal incidence and oblique incidence on the plate, the intensity distributions of the emergent light are obtained, as well as the relations between the thickness of the plate and the intensity distributions. Based on these relations, two methods to measure the thickness of the plate are proposed, and the phase difference between ordinary and extraordinary lights can be set precisely by rotating the plate around its optical axis.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"864 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123459558","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}

This paper proposes a new comprehensive interference assessment method, AHP-GRAP (Analytic Hierarchy Process - Grey Relational Analysis Process, AHP-GRAP) method. And the AHP-GRAP is applied to a real case to resolve the interference assessment problem in the high-speed railway wireless communication networks in this paper. In the proposed AHP-GRAP method, the relative weights of QoS (Quality of Service, QoS) criteria in the high-speed railway wireless communication networks are determined by AHP, and then these weights are used as coefficients of GRAP model. Based on the optimal value of the QoS in the high-speed railway wireless communication networks, GRAP is then used to perform the evaluation of interference. The results show that AHP-GRAP is a more comprehensive method to reflect the interference state of the systems than existing single criteria interference assessment algorithms.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123542678","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}
