Due to beam overlap, the detection zone of each ultrasonic sensor can be divided into three sub-zones, and also for a given obstacle distance, the uncertainty arc can be divided into three sub-arcs. First, considering obstacle detection range and efficient beam overlap, the geometrical constraints on an overlapped ultrasonic sensor ring are described. Second, the positional uncertainty of an overlapped ultrasonic sensor ring is expressed in terms of the areas of detection sub-zones, and Type I performance measure is defined as the area ratio among three detection sub-zones. Third, the positional uncertainty of an overlapped ultrasonic sensor ring is represented by the minimum area among detection sub-zones, and Type II measure is defined as the beam width of an ultrasonic sensor having the same amount of positional uncertainty. Fourth, the positional uncertainty of an overlapped ultrasonic sensor ring is represented by the averaged maximum arc length among detection sub-zones, and Type III measure is defined as the beam width of an ultrasonic sensor having the same amount of positional uncertainty. Finally, using a set commercial low directivity ultrasonic sensors, the changes of performance measures depending on the parameters of an overlapped ultrasonic sensor ring are examined and compared.","PeriodicalId":242298,"journal":{"name":"2012 IEEE International Symposium on Intelligent Control","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129190616","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, the effectiveness of RC decays when the time period of the RC does not exactly match with the period of the repetitive disturbance. RC also leads to reduced performance in between harmonics in terms of degraded sensitivity (more noise sensitive). High Order Repetitive Control (HORC) is an RC structure, which allows to shape the sensitivity function to make it either more robust for time period of the repetitive disturbances, or more noise robust. In addition, standard RC will also fail in systems with spatial repetitive disturbances, since the time period of this kind of repetitive disturbances may vary. Delay-Varying Repetitive Control (DVRC) can cope with spatial disturbances, however, it lacks the robustness attained by HORC. By combining these two RC structures, HORC and DVRC, a new Robust Delay-Variable Repetitive Controller (RDVRC) is obtained. The RDVRC is successfully applied to measurement data from a media transport system of an industrial printer. Robust DVRC will be useful for many motion control systems with repetitive tasks, as disturbances often repeat along the motion path.","PeriodicalId":242298,"journal":{"name":"2012 IEEE International Symposium on Intelligent Control","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134440418","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 mobile robotic sensors cover a bounded and connected two-dimensional arbitrary unknown region. An algorithm with decentralized control law has been developed to self deploy the mobile robotic sensors into a triangular lattice pattern ensuring optimization. The optimization of deployment in terms of minimum number of sensors ensuring 1-coverage and 6-connectivity(wherever possible) has been considered during final deployment of mobile robotic sensors over the arbitrary unknown region. A special consideration in continuation to the recent work has been taken in order to remove the redundant placement of mobile robotic sensors on the boundary of the region and to fully track the bounded smooth region. The concept of strongly connected quotient system of the decentralized control system has been used during line forming mode(s) inside the region. The algorithm is based on simple nearest neighbor rules derived from swarm intelligence. A number of numerical simulations have been done in order to validate the control algorithm.","PeriodicalId":242298,"journal":{"name":"2012 IEEE International Symposium on Intelligent Control","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121492180","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}
