This system is a First Order plus Time Delay (FOPTD) system, and the goal is to design a fractional order proportional integral (FOPI) controller. FOPI controller has three free parameters to achieve the desired performance. For this purpose, a stable region is obtained based on these free parameters which satisfy the desired phase and gain margins and flat phase constraints. And the proper parameters are selected based on this region. The main advantage of FOPI in comparison with traditional PID is its robustness. Computers simulations verify the robustness property and also show the effectiveness of the proposed FOPI controller.","PeriodicalId":444883,"journal":{"name":"The 3rd International Conference on Control, Instrumentation, and Automation","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114436667","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 concept of reaching an agreement based on local information, known as Consensus, has several quantitative aspects that can characterize the whole network behaviour. Among them, one of the pivotal features, is the consensus time - the time that it takes for the network to reach the agreement. Therefore a distributed adaptive scheme that can improve available consensus protocols in the case of consensus time is suggested.","PeriodicalId":444883,"journal":{"name":"The 3rd International Conference on Control, Instrumentation, and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122518195","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}

To meet the goals of algorithm, a new cost function is designed to satisfy the goal of the algorithm. Model predictive control has been used to provide this feature. Each robot's path planning would be based on solving a sequential optimization problem which determines that which of them follows the searcher and which of them position at most probable points.","PeriodicalId":444883,"journal":{"name":"The 3rd International Conference on Control, Instrumentation, and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127669301","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 dynamic parameters of the system are assumed to be unknown and it is desired that the line of sight of gimbal system tracks a reference input. Mechanical system is modeled in Adams-View software which simulates the exact behavior of gimbal system. The controller design is based on inverse dynamics approach which results in a non-SPR error model. To overcome the problem of non-SPR error model, an adaptive controller with modified error structure for updating the controller parameters is implemented. Simulation results on the gimbal system show superior performance of controller design in comparison to a classical PD controller.","PeriodicalId":444883,"journal":{"name":"The 3rd International Conference on Control, Instrumentation, and Automation","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115739135","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}
