The study aims at providing useful and new information on the possibilities and limitation of photovoltaic systems in buildings of historic importance to the operators working in the area. The research is based on the analysis of 117 surveys completed by officers working in planning departments in councils across England; including metropolitan districts, London boroughs, unitary authorities, counties and district councils. Results suggest that PV roof tiling systems currently only have a limited application as energy efficiency systems in buildings of historic importance. Consequently, they are only partially known by conservation officers. It also became evident that more succinct legislation on the installation of these systems to listed buildings would provide clearer objectives to the officers in charge of approving or rejecting applications. Lastly, it emerged that the whole system would benefit from stakeholders (such as Historic England and the UK Government) working together to provide more consistent approach when producing guidance documents.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"129 17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131897131","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 of the widely used fault detection mechanism is the so-called model based fault detection, where a model of the target system is involved to estimate the expected output of the system under healthy condition. Then a fault can be detected by comparing the actual measured output the estimated healthy output. By making use of the state estimation capability of observers, various observer-based fault detection schemes have been proposed to estimate the system output for the purpose of fault detection. However, it is worth noting that, different from state-feedback control, observer-based fault detection only concerns the output and it is not necessary to have a full state estimation. In this paper, a new type of observers, referred to as output observer, is proposed for fault detection, thus the unnecessary state estimation in observer-based fault detection can be avoided. First, an input/output system representation is developed to enable us build the output observer. Then a new approach of output observer design is presented, in which only the output variables are estimated instead of estimating any other system state variables. The application of output observer to fault detection in systems under disturbance is presented and systematic approach to design the FD scheme based on an optimisation method is given. This FD scheme is validated by simulating a model of a three wheels robot.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129557082","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 exploiting the differential flatness properties of the state-space model of the synchronous reluctance machine it is shown that a state-variables transformation (diffeomorphism) can be applied to it. This finally brings the model to an input-output linearized form, or equivalently to the so-called linear canonical Brunovsky state-space form. For the the transformed state-space description of the model the solution of the feedback control problem becomes possible after applying a linear feedback controller and the pole placement concept. Moreover, to solve the state-estimation problem and to implement state estimation-based feedback control through the measurement of specific state variables, the Derivative-free nonlinear Kalman Filter is used as a state observer. This is a new nonlinear filtering method, which consists of (i) the Kalman Filter recursion applied on the aforementioned linearized model of the synchronous reluctance machine, (ii) an inverse transformation based again on differential flatness theory which allows for computation of estimates of the state variables of the initial nonlinear model. Furthermore, to improve the robustness of the flatness-based control scheme and to compensate for model uncertainty or additive input disturbances that affect its dynamics, the Derivative-free nonlinear Kalman Filter is redesigned as a disturbance observer. The proposed control method is of proven global asymptotic stability and its efficiency is further confirmed through simulation experiments.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129935703","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 frequent situation in the engineering practice is that designers, final or intermediate users have to roughly estimate some basic performance data or specification data or other metrics related to the specific task they have, on the basis of few data available at a particular instant of time or at the time of use. This paper addresses this problem in the Industry 4.0 scenario by introducing innovative Design support system (DesSS), originated from the Decision Support System (DSS), for the prediction and estimation of machine specification data such as machine geometry and machine design on the basis of other heterogeneous parameters (i.e. motor performance, field of application, geographic market, and range of cost). For the development of the DesSS different machine learning techniques were compared such as Decision/Regression Tree (DT/RT), Nearest Neighbors (NN), and Neighborhood Component Features Selection (NCFS). Experimental results obtained on the real use case demonstrated the appropriateness of the application of the machine learning approaches as the main core of the DesSS used for the estimation of the machine parameters. In particular, the results show high reliability in terms of accuracy and macro-F1 score of the 1-NN+NCFS and RT for solving respectively the classification and regression task. This approach can viably replace the model-based tools used for the parameters prediction, being it more accurate and with higher computational speed.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132718945","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}

Up to date research of combustion devices focus on how to develop high efficient and “clean” device that can burn wide variety of fuels. The recent surge of interest in combustion of low calorific gaseous fuels has been derived, on the one hand, form the fact that fossil fuels shortfall will happen in near future, and on the other, there is constant struggle with tighten emission regulations. Low calorific gases are usually generated as side products in technological processes (i.e. blast furnace gas, waste gas from cupola and coke ovens, etc.), or can be produced in biomass gasification process or as a landfill gas and gas from mines. Low calorific gas can be burned in furnaces or boilers, in gas turbine combustion chambers or internal gas engines either with or without additional high quality gaseous fuel. Common problems associated with combustion of low calorific gaseous fuels are burning stability in rather narrow operating range, high cost of auxiliary equipment for safe operation of burner system and operation instability caused by variability of fuel content. Combustion within porous inert media (PIM) shows distinctive difference from open flame burning systems. This paper presents basic characteristics of combustion of low calorific gaseous fuels within PIM and discusses major parameters that effect on combustion stability, efficiency of the burner and GHG emission, as well as our own idea for development of this type of burner.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123768578","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 it is proven that the SRM's model is a differentially flat one. This means that all its state variables and its control inputs can be written as differential functions of key state variables which are the so-called flat outputs. Moreover, this implies that the flat output and its derivatives are linearly independent. By exploiting differential flatness properties it is shown that the 4-th order SRM model can be transformed into the linear canonical form. For the latter description, the new control inputs comprise unknown nonlinear functions which can be identified with the use of neurofuzzy approximators. The estimated dynamics of the electric machine is used by a feedback controller thus establishing an indirect adaptive control scheme. Moreover, to improve the robustness of the control loop a supplementary control term is computed using H-infinity control theory. Another problem that has to be dealt with comes from the inability to measure the complete state vector of the SRM. Thus, a state-observer is implemented in the control loop. The stability of the considered observer-based adaptive control approach is proven using Lyapunov analysis.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128822392","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}
