DF is a nonparametric state estimation method, where the filter is designed from the plant data directly. Direct filtering employs a clever strategy of averaging two nonlinear functions trained from the training data to obtain optimal filters for a restricted class of nonlinear systems, with the assumption that plenty of data is available. The filter can then be used to predict future states. While a clever idea, its nonparametric nature makes it slow. The authors propose to use Support Vector Machine (SVM) to suppress the size of data. Since SVM learns support vectors, the authors propose that the support vectors are the actual data of interest, and thus should be used for the nonlinear function estimation employed by the direct filter. Experimental results show good speedups with minimal degradation.","PeriodicalId":205599,"journal":{"name":"2014 IEEE Conference on Control Applications (CCA)","volume":"601 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131775125","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 relative velocity kinematic model is considered, hence making the method suitable for underwater vehicles where absolute velocities might not be available. The total position error vector has two components, the along-track error (tangent to the path) and the cross-track error (normal to the path). Two adaptive nonlinear observers are designed in order to estimate the current components w.r.t. the path-fixed frame and the origin of the error dynamics is shown to be globally κ-exponentially stable. The guidance algorithm uses this information and generates appropriate relative surge speed reference trajectories for minimizing the along-track error, while an augmented version of the line-of-sight (LOS) guidance is designed for minimization of the cross-track error. Moreover, the estimates from the nonlinear observers can be used to compute the ocean current vector w.r.t. the inertial frame.","PeriodicalId":205599,"journal":{"name":"2014 IEEE Conference on Control Applications (CCA)","volume":"Suppl 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128953292","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 model for the compression system is derived first and special attention is paid to an accurate description of the compressor map. Due to the strong coupling of the nonlinear dynamics of the compression system a nonlinear decoupling control concept is required. The presented approach is based on a gain-scheduled decoupling controller. The proposed control concept is validated with a complex nonlinear simulation model of an industrial compressor.","PeriodicalId":205599,"journal":{"name":"2014 IEEE Conference on Control Applications (CCA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133683798","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 objective is twofold: (i) compensation of harmonic currents and the reactive power absorbed by the nonlinear load; (ii) regulation the DC bus voltage of the inverter. First an adaptive observer is designed to estimate the network voltage which is not accessible to measurement and the unknown parameters of the network internal impedance. Second, a nonlinear controller that involves two loops in cascade, an inner-loop is designed, using the Lyapunov approach, to provide the harmonic compensation and an outer-loop is designed to regulate the DC bus voltage of the inverter. The controller performances are illustrated by simulation in Matlab/Simulink environment.","PeriodicalId":205599,"journal":{"name":"2014 IEEE Conference on Control Applications (CCA)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133416254","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}

One possibility is to predict the future wave elevation by combining its past history with the spatial information coming from a sensor which measures the free surface elevation up-wave of the wave energy converter. As an application example, the paper focuses on the prediction of the wave elevation inside the chamber of the oscillating water column (OWC) for the PICO OWC plant in the Azores, and two different sensors for the measurement of the free surface elevation up-wave of the oscillating water column were tested. The study showed that the use of the additional information coming from the up-wave sensor does not significantly improve the linear prediction of the chamber wave elevation given by a forecasting model based only on the past values of the chamber wave elevation.","PeriodicalId":205599,"journal":{"name":"2014 IEEE Conference on Control Applications (CCA)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132276130","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 prediction, and optimization phase of the linear model predictive controller are presented in detail. Simulation results, in the presence of realistic environmental disturbances, are given that demonstrate the performance and robustness of the controller. The proposed controller is compared with a modelbased controller that was developed for the same platform in a prior work, and the superiority of the former concerning the dynamic positioning capabilities, and the power consumption is shown.","PeriodicalId":205599,"journal":{"name":"2014 IEEE Conference on Control Applications (CCA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133132871","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}
