Consequently, there is a strong need in the process industry for non-invasive methods that can not only detect but also quantify stiction. In this work, a semi-physical valve stiction model is derived from the analysis of the dynamic response of a physical model. Based on the semi-physical model, we propose a noninvasive valve stiction quantification method using the routine operating data from the process. The algorithm is proposed to estimate the stiction parameters, namely static friction and dynamic or kinetic friction, without requiring the valve position signal. Quantification is accomplished by using linear and nonlinear least-squares methods which are robust and easy to implement. Several simulation examples, including both self-regulating and integrating processes with different degrees of stiction, are used to demonstrate the effectiveness of the method.","PeriodicalId":145065,"journal":{"name":"2013 American Control Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127674174","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}

An early-designed guidance law that orbits one UAV around the moving target is augmented with an additional term for coordination. This extra term, which can be computed based on the relative bearing angle between two UAVs, puts all UAVs into a balanced circular formation, where all agents spread evenly on a circle. Three communication topologies are considered, i.e., an all-to-all communication, a ring topology, and a cyclic pursuit topology. The effectiveness of the proposed cooperative target tracking control laws is demonstrated by numerical simulation examples.","PeriodicalId":145065,"journal":{"name":"2013 American Control Conference","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127676132","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 general gearshift of a DCT is divided into several stages for better dynamic derivation and controller design. Based on detailed dynamic modeling, the Model Reference Control (MRC) method is proposed and integrated into the traditional control logic together with PID control configuration so as to observe the best gearshift quality. Numeric simulations and parallel parameter optimization is proceeded on Matlab platform. The results demonstrate that the MRC method applied on DCT clutch control can evidently reduce both the jerk shock and frictional loss of dual-clutch operations, which proves MRC method as a wise choice of DCT controlling strategy. Meanwhile, several theoretical predictions have been verified by the simulation curves to show the effectiveness of MRC again.","PeriodicalId":145065,"journal":{"name":"2013 American Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126354305","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}

Our experiments show that these proposed visual evaluation criteria successfully measure changes in scenes and our camera selection method effectively reduces camera switching when compared to other state-of-the-art methods.","PeriodicalId":145065,"journal":{"name":"2013 American Control Conference","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126202233","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 show that the stability of the observer is guaranteed independently of the switching sequence.

We pose the problem of resource allocation as a linear-quadratic game with many dynamically coupled zone occupants(agents) and an uncoupled social planner. The social planner influences the game by choosing the quadratic dependence on control actions for each agent's cost function. We propose a neighborhood-based simplification of the dynamic game that results in a more realistic and scalable framework than is considered in standard dynamic game theory. In addition, we construct the pricing design problem as a convex feasibility problem and apply our method to an eight zone building model.","PeriodicalId":145065,"journal":{"name":"2013 American Control Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125704721","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 proposed solution is a new Kuramoto-like model for multi-robot coordination, in which the standard sine-terms have been replaced by cosines. This new interaction model enables the balanced deployment of agents on a circle, while only taking into account the local information of each agent's two neighbors on a cycle graph. This means that individual agents do not need to know the (relative) states of all agents nor how many other agents are indeed present in the network. We illustrate the operation of the proposed protocol in simulation as well as extend it to a nonlinear scenario by optimizing over the coupling weights.","PeriodicalId":145065,"journal":{"name":"2013 American Control Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125738791","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}

Recently there has been investigation of barrier methods for the solution of NUM which have been shown to posess second order convergence. However, the question of accelerating dual decomposition based methods is still open. We propose a novel semismooth equation approach to solving the standard dual decomposition formulation of NUM.We show that under fairly mild assumptions that the approach converges locally superlinearly to the solution of the NUM. Globalization of the proposed algorithm using a linesearch is also described. Numerical experiments show that the approach is competitive with a state-of-the-art nonlinear programming solver which solves the NUM without decomposition.","PeriodicalId":145065,"journal":{"name":"2013 American Control Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115863142","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}
