Based on each robot formation feedback between itself and its virtual structure and artificial potential field method, a decentralized controller is designed to maintain the formation to effectively track the target with desired velocities and avoid collisions. The formation control stability is proved with Lyapunov stability theory as well. Finally, the validity of the proposed formation controller is demonstrated with experiment simulation results in the case of six followers.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131651634","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 recent years, some statistical research on human correspondence has proven that the inter-event time distribution satisfies a power law, but the judgment for scaling exponent is still controversial. In this paper, we collect communications data from Sui Gu and Van Gogh and find the inter-event time distribution fits a power law with exponent 1.5, which is in accordance with Barabási's conclusion. In addition, the inter-event time distribution about two men's letters for 5 consecutive years also follows Power-law distribution with the same exponent.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116164152","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 novel design approach to the optimal control law is proposed. By constructing a new state vector, the original system model and the performance index are simplified to equivalent ones without time-delay. So the infinite dimension problem of optimal control for systems with time-delays is avoided. The optimal control law is found by solving a matrix differential equation instead of a two-point boundary value problem, Simulation results demonstrate the effectiveness of the optimal control approach.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120940159","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 approach is an optimized version of the circuit simulation method, which we proposed in one previous paper. Both the optimized and the original methods solve the graph isomorphism problem through circuit modeling and simulation. The simulation result, a series of node voltages, is taken as the identification index for a graph and isomorphism is determined by comparing the indices of two graphs. In general, circuit simulation needs a reference node. In the original method, each vertex takes turns to serve as reference, which leads to inconvenience and complexity in computation; in the optimized version, an extra vertex is added to the graph to work as a reference node in the circuit, which simplifies computation and the form of identification index, thus enhancing the efficiency. Both methods are tested on a large number of random undirected graphs generated by the computer and the experiment result shows that the runtime of the optimized method is much lower than that of the original one.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127142566","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 feasible data set is achieved on the basis of dynamic characteristic of PID control loop. With defined ε-insensitive loss function and identification confidence function, the valid data set for model identification is selected from the feasible data set. The valid data set is used to model process objects and then a PID parameters tuning method is given which has a multiple models structure. By using developed optimal stochastic Luus-Jaakola algorithm, an optimized PID controller is obtained which has a perfect effect for all the models. The work of the algorithm does not require staff participation, and the obtained PID parameters can be directly applied to the control loop without a further adjustment. This algorithm has been used in many production plants successfully, and produced satisfactory results. The actual results show that this is a practical algorithm of PID parameter tuning with obvious advantages of simple use and convenient promotion.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128772999","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}
