Several examples are considered that illustrate the approach.","PeriodicalId":193106,"journal":{"name":"SIAM Conf. on Control and its Applications","volume":"10 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132400174","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}

Where non-quadratic terminal payoffs are required, these techniques fail due to the attendant nonquadratic value functions involved. In order to compute these non-quadratic value functions, it is often necessary to appeal directly to dynamic programming in the form of gridor element-based iterations for the value function. These iterations suffer from poor scalability with respect to problem dimension and time horizon. In this paper, a new max-plus based method is developed for the approximate solution of discrete time linear regulator problems with non-quadratic payoffs.","PeriodicalId":193106,"journal":{"name":"SIAM Conf. on Control and its Applications","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123522809","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}

We formulate the problem as an optimization problem with time-varying cost function. We examine the case where a group of elevated imaging sensors look down to and form the map of a 2-dimensional environment at a pre-specified resolution. The sensors solve an optimization problem that attempts to optimize a time-varying cost function. The cost at any time instance measures the distance between the desired resolution function and the achieved resolution until the previous time instant. We discuss the numerical implementation challenges of this approach and demonstrate its performance on a numerical example.","PeriodicalId":193106,"journal":{"name":"SIAM Conf. on Control and its Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121977045","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, it is not well understood how significant the role of the communication link is in improving the system performance and how the network structure influences the robustness of the interconnected system. In this paper, we first demonstrate via a numerical simulation that certain communication links of the distributed control play important role in improving the overall system performance. Next, based on eigenvalue sensitivity analysis, we characterize those links explicitly for interconnection of scalar identical subsystems with ring and uniform extended star physical topologies. We further apply the method to investigate the relation between network robustness and the physical interconnection topology under some local perturbations. It is observed that there exists a trade-off between designing an interconnected system with high robustness and low communication cost for the considered topologies.","PeriodicalId":193106,"journal":{"name":"SIAM Conf. on Control and its Applications","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115619252","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}
