An off-line analysis of the frequency variation is presented. This analysis was done using real data extracted from the Mexican Grid during August 2004. It is shown that, although the Kalman indexes do not converge to an exact value, they maintain a low variation following the initial iterative steps. The precision of the estimation is limited by unknown load disturbances but this technique could be useful to predict the frequency variation and also the load variation of the Mexican grid.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132468830","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}

In this sense, most of the mobile robots fuse odometry sensors with laser range finders or sonar sensors. Nevertheless, the odometry and kinematic model error statistics are usually unknown and time variant. An Adaptive Extended Kalman Filter is proposed for Mobile Robot Localization and the first and second moment of odometry sensors noise estimation.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134445919","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}

The model-based verification techniques use models to describe the possible system behavior in a mathematically precise and unambiguous manner. In particular model checking provides the basis for a whole range of verification techniques ranging from an exhaustive exploration to experiments with a restrictive set of scenarios. Here we propose a framework for verifying mechatronic-design systems based on symbolic model checking. Moreover this framework is an approach based on a novel semantics called p-stable.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128902464","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}

For a static target wecharacterize the global closed loop attractor using the dynamicrobot and vision model, and prove global asymptotic stability ofposition error for the control scheme, the so called position-basedvisual servoing.
