The complex whole problem has been divided in smaller more manageable subproblems (e.g. model identification, control structure selection, control design, etc). However this presents several problems: i) issues arising from the interrelation between subproblems of the reductionist approach are neglected, ii) recent advances in identification for control have arisen the necessity of tackling the identification and control design in an unified approach, iii) in order to design automatic supervisors high level issues must be considered. Consequently we face the holistic control design problem. First the elements of the problem are defined and their relations established. Secondly we proposed a new scheme for dynamic management of information flow of the control design problem. It provides a structured approach to consider all the important aspects of the control design. It is suited for automatic supervisory schemes design","PeriodicalId":347035,"journal":{"name":"2006 14th Mediterranean Conference on Control and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128815900","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}

A robust 'detection and labeling algorithm' for the correct identification and sorting of the optical markers is proposed; a sorted list of marker positions is then provided as input to the 'pose estimation' algorithm. A detailed study of the performance of two specific 'pose estimation' algorithms (GLSDC and LHM) is performed with special emphasis on the required computational effort as well as on the robustness and error propagation characteristics. Extensive simulation studies demonstrate the performance of the LHM and GLSDC algorithms and show the importance of a robust 'detection and labeling' algorithm.
