In the present work, fuzzy logic controllers (FLCs) are used and examined via extensive simulations. A main weakness of the FLC approach is how to ensure system stability, and the main contribution of the paper is that a nonlinear model-based analysis is performed to cover this gap. Particularly, it is proven that for the entire EV system, the input-to-state stability (ISS) property holds true with respect to arbitrary external inputs, namely the external mechanical torque on the car wheels and the internal battery voltage. Furthermore, it is shown that the system is ISS and its states converge to the equilibrium regardless from the way the controlled-inputs are constructed. This decisively enhances the overall design approach since it is proven that FLCs applied on the EV, simultaneously guarantee system stability.","PeriodicalId":395329,"journal":{"name":"2017 Twelfth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121459173","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 the thrust ripple separation, the on-load thrust ripple is divided into three components, which stem from different causes respectively. Although the longitudinal end effect is the biggest cause, the DC current is another great factor because of the aggravated magnetic saturation level particularly under flux-weakening condition, which is totally different from traditional hybrid-excited machine. To on-load d-axis and q-axis (d-q) inductances, they also vary along with the increase of DC excitation current. Moreover, their difference is not zero and excitation level dependent, which indicating the on-load reluctance force cannot be neglected. The results are beneficial to optimization design and parameter identification of HEFSLMs.","PeriodicalId":395329,"journal":{"name":"2017 Twelfth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115080617","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 design methodologies of the conventional PI-based controller, the Taylor series expansion linear approximation based (TSLA-based) controller and the feedback linearization based (FL-based) nonlinear controller are provided. The objective is to keep the wind turbine operating at its optimum rotor speed (MPPT control), while insuring the power transfer from the turbine to the generator, regardless of the wind speed. The controller gains of the nonlinear controller are determined via Linear Quadratic Optimal Control (LQOC) approach. The results show a better control performance for the nonlinear controller. This performance is characterized by fast and smooth transient responses as well as a zero steady state error and reference tracking quality.","PeriodicalId":395329,"journal":{"name":"2017 Twelfth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133686079","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 contribution of the paper is focused on the impacts of charge/discharge DC-current's frequency, the temperature and the number of cycles on supercapacitor resistance and capacitance. The proposed method uses several DC-current profiles based on fluctuations and no fluctuations consideration. To do the supercapacitor stress tests, the experimental tests based on charge and discharge operations with fluctuating DC-current are done. To do estimation of the series resistance and capacitance (characterization) a constant DC-current without any fluctuations consideration is used.
