The traffic is differentiated by its destination (i.e. Lagrangian flow) and different flow groups are assumed to satisfy the first-in-first-out (FIFO) condition at each junction. We show that our model leads to a well-posed problem for computing the dynamics of the system and prove that the solution is unique through a mathematical derivation of the model properties. The framework is then used to analytically prescribe the delays at each junction of the network and across any sub-path, which is one of the contributions of the article. This is a critical requirement when solving control and optimization problems over the network, such as system optimal network routing and solving for equilibrium behavior. In fact, the framework provides analytical expressions for the delay at any node or sub-path as a function of the inflow at any upstream node. Furthermore, the model can be solved numerically using a very simple and efficient feed forward algorithm. We demonstrate the versatility of the framework by applying it to a diverge junction with complex junction dynamics.","PeriodicalId":223665,"journal":{"name":"2015 American Control Conference (ACC)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124511954","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}

Taking each supercapacitor cell as an agent in multi-agent systems, the voltage equalization problem can be formulated as a cooperative tracking problem. The sparse communication network among the super-capacitors in the cyber layer can be modeled by a digraph. As the voltage changes within a limited range, a general saturation function is put forward to guarantee the boundedness of the control input. Based on the nearest neighborhood rule, a bounded voltage equalization controller with tunable control gains is designed accordingly. The proposed voltage equalization methodology is distributed and not using a central controller. Each super-capacitor cell only need its voltage information and its neighbors, the desired control objective can be accomplished by local interaction in a cooperative way. Under the assumption that the digraph has a spanning tree, the asymptotically stability of the overall close-loop system is rigorously proved with the aid of a novel Lyapunov function integrating Lasalle invariant principle. The voltage equalization has been achieved by the proposed cooperative control approach, which is verified by the simulations. under different initial conditions, cooperative objectives and different network sizes.","PeriodicalId":223665,"journal":{"name":"2015 American Control Conference (ACC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126235772","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}

Yet cells manage to have precise timing of important events. Here, we study how gene expression could possibly be regulated to precisely schedule timing of an event around a given time. Event timing is modeled as the first-passage time (FPT) for a protein's level to cross a critical threshold. Considering auto-regulation as a possible regulatory mechanism, we investigate what form of auto-regulation would lead to minimum stochasticity in FPT around a fixed time. We formulate a stochastic gene expression model and show that under certain assumptions, it reduces to a birth-death process. Our results show that when the death rate is zero, the objective is best achieved when all of the birth rates are equal. On the contrary, when the death rate is non-zero, the optimal birth rates are not equal. In terms of the gene expression model, these results illustrate that when protein does not degrade, stochasticity in FPT around a given time is minimized when there is no auto-regulation of its expression. However, when the protein degrades, some form of auto-regulation is required to achieve this. These results are consistent with experimental findings for the lysis time stochasticity in λ phage.","PeriodicalId":223665,"journal":{"name":"2015 American Control Conference (ACC)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126237093","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}
