Conventional control approaches, such as proportional-integral (PI) control, are well-suited for steady-state operation without system constraints. In this work, we investigate the ability of model predictive control to enable larger transient thermal loads subject to tighter temperature limits through anticipation and load-shedding. Our results include (1) a linear model predictive control validated on a nonlinear model of the vapor compression system, and (2) direct comparisons to state-of-the-art PI control for stressing scenarios.","PeriodicalId":137983,"journal":{"name":"2016 American Control Conference (ACC)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125184472","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}

First, the actuator faults are modeled via a polytopic uncertainty method. Second, a distributed observer is designed for the single agent by sharing the communication network sensors to estimate the state information. Then by these estimated information, a robust consensus reliable control protocol against actuator faults is obtained and desired disturbance rejection performance can be guaranteed by this proposed protocol. Third, the non-convexity conditions of the consensus control protocol can be translated into a LMI optimization problem via simple matrix calculation. Finally, the effectiveness of the proposed reliable controller scheme is illustrated by the example.","PeriodicalId":137983,"journal":{"name":"2016 American Control Conference (ACC)","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123258222","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 paper studies the parameter estimation problem for dynamical systems based on the sinusoidal frequency response experiment. Because the output response is a nonlinear function with respect to the parameters to be estimated, a nonlinear criterion function is constructed for finding the parameter estimates. Using the nonlinear optimization technique, we present an iterative algorithm for estimating the system parameters. In order to overcome the problems of singular and ill-conditioned matrix during the iterative process, we put forward a damping iterative algorithm. Finally, an example is provided and the simulation results indicate that the proposed method has good performance.","PeriodicalId":137983,"journal":{"name":"2016 American Control Conference (ACC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125553652","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}

By replacing the single transducer in a stethoscope with a dual piezo transducer assembly, it is shown that an inverse dynamic mapping can be used to relate the two measured signals to original directional inputs acting on the stethoscope. Specifically, model inversion is used to estimate and remove physician handling noise from chest sound signals. An experimental test platform which uses a vibration shaker to simulate the desired auscultation signal is used to experimentally demonstrate the feasibility of the dual-piezo stethoscope approach in improving auscultation.","PeriodicalId":137983,"journal":{"name":"2016 American Control Conference (ACC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115076020","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 phase shift between the desired force signal and the applied force to the specimen is irrelevant for keeping the force within the fatigue testing requirements considered here. Thus, the proposed approach relies only on an appropriate amplitude and mean value tracking control, disregarding the phase. An estimator for the amplitude and mean value of the output force signal is proposed based on a demodulation technique. Global exponential stability of the complete error system with respect to a small residual set is guaranteed via averaging analysis, for the plant operating at low frequencies. Experimental results and numerical simulations performed at the Non-destructive, Corrosion and Welding Laboratory (LNDC/COPPE/UFRJ) illustrate the remarkable behavior of the proposed scheme, considering real fatigue testing machines.","PeriodicalId":137983,"journal":{"name":"2016 American Control Conference (ACC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116559224","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 propose a bi-directional middleware that allows the optimal utilization of the common resources for the benefit of either or both the layers in order to obtain overall system performance. This has been implemented over Etherware, a prior developed separation-based middleware for networked control systems as the bridge between the layers. Our implementation employs a Resource Manager module to handle common resources between the layers on Etherware. A case study of network connectivity preservation in vehicular formation control illustrates how this approach applies to particular situations of interest.","PeriodicalId":137983,"journal":{"name":"2016 American Control Conference (ACC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122529404","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}
