A finite state Markov chain with partially known transition probabilities is used to model random communication delays between sensors and controller. Based on Lyapunov-Krasovskii functional, a novel methodology for designing a partially mode delay-dependent output feedback controller is proposed. Using cone complementarity linearization algorithm bilinear matrix inequalities (BMIs) are solved to obtain the controller gains. We also show that the results for completely known transition probabilities and completely unknown transition probabilities can be derived as special cases of our result. The effectiveness of the proposed design methodology is demonstrated by a numer ical example. To the best of authors' knowledge, the problem of designing an output feedback controller for a partially known transition probability has not been fully investigated.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127784222","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 consensus reference is taken as a virtual leader, whose output is available to the leader of the group. The proposed approach is based on the estimation of consensus reference and decentralized tracking control, where each agent communicates with their neighbors, estimates the consensus reference, and make a control decision based on the estimated consensus reference. Challenges of the approach include the design of decentralized adaptive tracking control assuming each agent has knowledge of the consensus reference in the presence of mismatched uncertainties, and the design of estimators that allow agents to make correct estimations of the consensus reference. Sufficient conditions are given to ensure output consensus tracking is achieved. Simulation results show satisfactory performances.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127817648","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 control design is based on discrete direct adaptive neural control, where the neural controller parameters are adapted using Lyapunov based tuning laws. There is no explicit identification phase in this control scheme, and the resulting controller operates directly on measurements without a state estimator. Performance of the proposed control scheme is evaluated on a full-scale nonlinear three-dimensional base-isolated benchmark structure incorporating lateral-torsion superstructure behavior, and biaxial interaction of nonlinear bearings. The results show that the proposed controller scheme is capable of achieving good response reductions for a wide range of near-fault earth quakes, without corresponding increases in the superstructure responses.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134644428","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 geometric moments, encoding an abstraction of the swarm, are controlled via a nonlinear gradient descent to match those of a discrete set of particles describing the occurrence of some event of interest to be monitored. Because of its limited sensing capabilities, each agent can measure the position of only a subset of the overall particles, from which it locally estimates the desired moments of the swarm running a proportional-integral (PI) average consensus estimator. The closed-loop stability of the system arising from the combination of the gradient-descent controllers and the consensus estimators is studied and simulation results are provided to illustrate the proposed theory.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127223677","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 robust performance criterion defines allowed and forbidden regions for the controller frequency response on the RCBode plot. The nonlinear system is linearized about a finite set of operating points which are considered to be a set of structured uncertainties. The union of the forbidden regions of each linearized system then defines the RCBode plot of the nonlinear system. We apply an iterative loop shaping technique to eliminate the intersections between the forbidden regions of the RCBode plot and the frequency response of the controller. We demonstrate the effectiveness of this technique for the design of a flow-rate controller for a dynamic nonlinear butterfly valve system. We show that this design is less conservative than a design satisfying the Circle Criterion. Finally, simulations are presented which verify the performance of the compensated system.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133812645","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 addition, string stability of a platoon of vehicles equipped with such an ACC controller has been taken into consideration and parameter constraints of the controllers are derived to mitigate steady state error propagation.

Useful models should accurately predict the work production of these flexible utilities. A framework for such a model is a class of bilinear models for estimating the efficiency of complex and flexible energy utilities [9], This framework, which we call Energy Conversion Networks (ECN), may be used to determine financially optimal operating conditions and opportunities for financial and operational hedging by the utility operator [8], [10]. Given an ECN model, we compute a unique input-output mapping from the decision variables and heat input to work output. Multiple network realizations may be possible from a given input/output model. Work output from these models are expressed as rational functions of entropy flux with parameters of temperatures, thermal conductances, and engine efficiencies. Using plant data from a report published by the California Energy Commission [6], we demonstrate fitting this data on several network realization examples. We use measured work output as a function of heat input to calibrate a model. Heat rate curves are the most common way these data are typically available. We developed a data fitting procedure to determine the parameters resulting in the best calibrated model given a particular network model and data set.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"322 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124562244","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 this paper, an intervention strategy is proposed for the S-system model.
