In this work, a Kalman filter is proposed to estimate vehicle sideslip using tyre force measurements. Most of the vehicle sideslip estimators do not use tyre force measurements and are based on tyre force model. Because of the tyre force model nonlinearities and uncertainties, the estimator accuracy depends highly on factors such as tyre-road friction, vertical load, temperature, tyre pressure, etc. Therefore availability of tyre force measurements offers benefits in vehicle sideslip estimation. The proposed estimator also has advantage over accelerometer based estimators as the later can have estimation errors from roll and pitch dynamics. The estimator is studied in a multi-body vehicle simulator for various maneuvers.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114753365","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 suggested controller does not include explicit attitude feedback, thus eliminating the need for accelerometers which are susceptible to vibrations, and complex attitude estimation algorithms. Furthermore, linear velocity measurement which can be difficult to achieve in indoor environment is not required to damp the system. A model for the hovercraft and visual measurements is presented, and stability analysis of the suggested controller is performed and supported by a complete six degrees of freedom simulation.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127241999","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 controller is formulated based on the bijectivity between the Voltage and Power in the PV generator (PVG) characteristic; therefore if the optimal voltage is reached, this means that the maximum of power is obtained. The proposed MPPT algorithm is implemented on a dSpace DS1104 controller board. In order to demonstrate the efficiency of the proposed algorithm in real time, an experimental setup using a boost converter connected to a resistive load is successfully implemented and studied. The obtained experimental results prove the validity of the proposed MPPT algorithm.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126078713","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 most published approaches, RH control is associated to model predictive control and amounts to minimize a cost defined over an horizon that slides in time. The optimization is done with respect to a sequence of candidate values for the manipulated variable, of which only the first is used. When considering nonlinear control problems, if the candidate sequence of the manipulated variables is left free of any constraint related to the plant dynamics (apart from operational constraints), there is the danger that the numerical method used converges to a local minimum. In this paper, instead, the minimization is performed using a relaxation algorithm that approximates the solution of Pontryagin's optimality conditions. This approach has the advantage of shaping the solution using the state and adjoint equations and, in addition, provides a natural approach to continuous RH problems. This algorithm is applied here to design therapies for tumor growth, modeled by the Gompertz model. A comparison of quadratic costs with costs that lead to sparse control signals, i. e. that are zero instead of assuming a small value, is also done.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121917734","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 order to address this situation, a state observer approach based on a model including temperature effect and an Extended Kalman Filter is proposed. Noting indeed that temperature affects some equivalent straight length of the pipe, which is used in the model, the observer estimates it together with the leak coefficients. This approach only considers head pressure and flow rate measurements coming from pipeline ends, likewise, water temperature measurement at upstream tank. Results with real data obtained from a pipeline prototype are shown in two different ways in order to illustrate the performance of proposed leak isolation system, as compared to the traditional approaches found at literature.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121966886","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}

With such a model, a DES is observed partially by observers, and secrecy preservation of a property (on information-flow) is modeled as the impossibility for observers to determine whether executed event sequences belong or not to a given language. This model of secrecy has then been adopted to study secrecy by using a Unifying Decision-Making Framework (UDMF) which has been recently developed; a centralized architecture has been used. In the present paper, we generalize the study with decentralized architectures, and compare our results with those obtained with a centralized architecture.","PeriodicalId":316642,"journal":{"name":"2015 23rd Mediterranean Conference on Control and Automation (MED)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125591091","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}
