The output voltage characteristics of six systems are compared. Experimental results show that DEFC systems present variable, nonlinear impedances as a function of frequency. It is shown, through experimental results, that DEFC systems do not exhibit predictable output as function of duty cycle alone. Consequently, output voltage control through pulse width modulation (PWM) techniques cannot be employed for DEFC systems.. The motivation for this analysis is a preliminary investigation into the use of DEFC's as a power source for a prototype Martian Uninhabited Aerial Vehicle (UAV).","PeriodicalId":345424,"journal":{"name":"2007 IEEE Vehicle Power and Propulsion Conference","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127333313","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}

To compute the forces, many analysts utilize the finite element (FE) method to compute the vector fields followed by the Maxwell stress tensor (MST) approach to calculate forces from the fields. Although the FE/MST approach has been used for decades, it does have a shortcoming in the computational requirement of the FE method, which limits the approach to a tool for analysis rather than for comprehensive machine design. To address this, a new so-called Enhanced Field Reconstruction Technique (EFRT) has been developed. Using the EFRT, the fields inside a machine are computed using a minimum number of FE evaluations. Using the results, a set of basis functions are established that enable the calculation of forces inside the machine under arbitrary excitation and rotor position. The EFRT greatly reduces the computational effort required to compute the vector forces inside machines with an accuracy similar to the FE method.","PeriodicalId":345424,"journal":{"name":"2007 IEEE Vehicle Power and Propulsion Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116702790","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 destabilising element associated with a constant power load is eliminated by reformulating the system dynamic equations in terms of the rate of change of energy, or instantaneous power. A power shaping control strategy is employed to regulate the output voltage, while maintaining large-signal system stability under all operating conditions. The proposed control strategy is simple, and easy to design and implement. Its utility and effectiveness are demonstrated by simulations and experiments.","PeriodicalId":345424,"journal":{"name":"2007 IEEE Vehicle Power and Propulsion Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132379749","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 system can be divided into two parts: one is for the vehicle management that is related with the supervision of the vehicle operation and the other is for the vehicle operational control that is placed in the lower position of the control hierarchy. In this paper we focus on the vehicle operational control scheme that is one of the important features of PRT to guarantee PRT system performance. The operational control scheme that can be implemented by using the commercial process boards is proposed and a simple vehicle control algorithm for test is uploaded to it. The calculation results of the process boards are compared with the simulation results that are produced from a combined platform of Matlab/Simulink and Labview Simulation Interface Toolkit.","PeriodicalId":345424,"journal":{"name":"2007 IEEE Vehicle Power and Propulsion Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116778886","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}

Energetic macroscopic representation (EMR) is used to organize the numerous blocks required. A Petri net is employed to activate a model according to clutch state (lock and slip).

A multi-section stator winding and interleaved rectifier arrangement is introduced that enables high power levels to be achieved using small semiconductor devices, and which greatly reduces the output filter capacitor requirements. We also demonstrate control methods suited to this interleaved system. In addition to accurate closed-loop output voltage control, we introduce methods to provide (partial) synchronous rectification for reduced loss, and to provide tight load dump transient control. The proposed technology is validated in the design and experimental evaluation of a 42 V, 3.4 kW alternator with fully integrated power electronics and controls. The prototype alternator achieves approximately a factor of 2.1 increase in power and 1.6 increase in power density as compared to a conventional diode-rectified alternator.","PeriodicalId":345424,"journal":{"name":"2007 IEEE Vehicle Power and Propulsion Conference","volume":"2021 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115880728","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 Illinois Institute of Technology (IIT) decided to field a team in the competitions inaugural year. A true passion for designing, improving, and racing Hybrid Electric Vehicles (HEVs) has evolved at IIT from this remarkable experience. The team was named ACE for it primary sponsor, the Armour College of Engineering and performed beyond expectations by achieving a podium position in dynamic events. The competition provided students a fun environment to learn not only about HEVs and what it takes to build one, but also what teamwork and steadfast dedication can accomplish. A first time entry in formula competitions, launching a project like Formula Hybrid proved to be a demanding task for the ACE Team. This paper discusses the many stages of the ACE Team that spanned over 9 months providing insight into what it actually takes to participate in a competition of this nature while providing recommendations on how to go about it more efficiently. The paper also provides a review of the hybrids developed by other schools for the competition.","PeriodicalId":345424,"journal":{"name":"2007 IEEE Vehicle Power and Propulsion Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127459373","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}
