On the other hand, reset control is able to overcome fundamental limitations of linear and time invariant controllers, and thus a reset controller, a standard linear controller that, at some instants, resets to zero its internal states, may be designed to simultaneously improve speed of response and robustness. In this way an efficient solution can be enhanced by the application of reset controllers to brake systems. In a recent work presented by the authors is defined a wheel slip reset controller, based on a PI+CI controller, versatile and with a simple design, that simultaneously presents improved performance, decreasing the braking distance in several road conditions while maintaining as far as possible appropriate driving characteristics of the vehicle, and also is robust against technological limitations such as model uncertainties, actuator saturation and time delay in communications. This paper presents some ideas about the analysis and tuning of this wheel slip PI+CI reset controller.","PeriodicalId":287492,"journal":{"name":"2015 International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles (ESARS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125578504","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}

Here, DAB is a part of a three phase 10kW bidirectional on-board charger in electric vehicles (EVs). It is an isolated interface to the battery placed after a three phase power factor correction (PFC) stage. 1200V rated SiC JFETs in the H-bridge at the DC link side of DAB enable operation at high voltage values of the DC link (above 500V) with high switching frequencies in the range from 50 to 150 kHz. Both high converter efficiency and simplified, compact converter design can be achieved thanks to the application of these wide band gap (WBG) devices. Furthermore, the control algorithm is presented to achieve the fast reference tracking even in the case when, due to simplicity of sensing, only average values of currents of both battery and DC link are being regulated.","PeriodicalId":287492,"journal":{"name":"2015 International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles (ESARS)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131917601","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}

Their adoption is expected to bring new solutions in terms of Power Quality and integration of energy storage systems and electronic drives on board. The increasing interest in high-power onboard applications, such as in ships or railway transportation, led to the rise in voltage levels, which in turn caused an increase in short-circuit currents; therefore, a careful assessment has to be done to design system protections. Moreover, in onboard power systems, a continuous connection to the grid is not feasible (except in rare cases, such as trains), so power generation is usually made using rectified synchronous generators. The absence of a constant-voltage infinite-power bus complicates short-circuit currents calculation, making necessary to consider generators internal dynamics during short circuit transients. In this paper two different approaches to evaluate DC short circuit currents are proposed. A dual validation is done, through a first comparison with IEC 61660-1 Standard and then using time-domain simulation of a circuit model, under the constant supply voltage hypothesis. Then, the synchronous generator supply is considered, and its internal dynamics impact on DC short-circuit currents is assessed. Proper case studies are presented, to show the differences between the proposed approaches.","PeriodicalId":287492,"journal":{"name":"2015 International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles (ESARS)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115778067","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}
