Thus, a compensation strategy is necessary to solve the drift voltage problem of the NPP. The traditional compensators overcome the drift voltage problem by adjusting an offset voltage. Since there is no theoretical basis to determine the gain of the offset voltage, it may cause the over-adjustment. It is also difficult to master the law of the output waveform adjusted by the offset voltage. Given these defects of the traditional compensators, a new compensation factor (CF) is raised and the relationship of the CF, the NPP, the phase current and the Dc-link capacitors is analyzed in this paper. By adjusting the CF in a limit region analyzed in this paper, the drift voltage problem is well solved without over-adjustment. Since it is easy to know the law of the output waveform adjusted by the new CF, it can also decrease the switching frequency and avoid the three level modulation degrading to the two level modulation in some operation conditions. Simulation results verify the correctness and effectiveness of the proposed method.","PeriodicalId":6597,"journal":{"name":"2017 IEEE 26th International Symposium on Industrial Electronics (ISIE)","volume":"56 1","pages":"893-898"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85459484","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}

Performance of this controller is compared to that of the controller employing the extended Kalman filter and the linear-quadratic regulator and the controller designed for polynomial systems confused with white Gaussian noises.","PeriodicalId":6597,"journal":{"name":"2017 IEEE 26th International Symposium on Industrial Electronics (ISIE)","volume":"21 1","pages":"466-471"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81889022","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}

This is primarily due to the introduction of temperature tolerant, high energy rare earth magnets over the past two decades. The proposed magnetic configuration presented in this paper introduces an opportunity for optimal generation of electromagnetic torque. Our investigation shows that the proposed configuration can reach the power and torque densities similar to those of the interior magnet PMSM using ferrite magnets of the same volume. This will allow for removal of the need for high energy rare earth magnets, thereby allowing for sustainable production of high grade PMSM drives. The key aspect in the magnetic design of the machine deals with the tangential formation of the flux lines inside the rotor which in turn will increase the motional forces while mitigating the undesirable radial forces acting on the stators.","PeriodicalId":6597,"journal":{"name":"2017 IEEE 26th International Symposium on Industrial Electronics (ISIE)","volume":"37 1","pages":"342-347"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79455894","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 the literature, frequency-domain approaches are widely treated. They are often based on the injection of a perturbation on the cell current, which allows determining the cell impedance through the joint analysis of the cell current and voltage. The perturbation can be sinusoidal, with its frequency varying into an assigned range, or more complex. The sinusoidal current and voltage signals used in classical electrochemical impedance spectroscopy can be used also for identifying the key parameters of an equivalent circuit of the fuel cell. This procedure, which is based on a suitable Kalman filter, allows to detect fault conditions affecting the cell, such as drying and flooding. The proposed approach allows to predict a possible fault before the long processing of the huge amount of data needed by the impedance spectroscopy is available.","PeriodicalId":6597,"journal":{"name":"2017 IEEE 26th International Symposium on Industrial Electronics (ISIE)","volume":"13 1","pages":"934-939"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79650795","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}

This is to reduce discomfort for users by high back drivability. In the case of a device in which the motor itself moves, the motor needs to be lightweight.

The tracker is dual axis with a concentration ratio of 160 and a small acceptance angle of 2 degrees, hence a precise tracking control is required. Two control schemes were developed and tested, the open loop and closed loop. A sun position algorithm was used for open loop control whereas a sun sensor was used for closed loop control. The control system were simulated using Matlab/Simulink. It was found that open loop tracking is simpler to implement and consumes less power but is also less accurate and tracking error accumulates over time. On the other hand, closed loop control is more complicated to implement, consumes more power is much more accurate than open loop control. So, it is recommended to use the closed loop controller for PFFC system. The individual components of the control system were modelled using generic Simulink models. The complete model was operated in both open loop and closed loop configurations. The results of the models were analysed to estimate the operating limits of the tracker.","PeriodicalId":6597,"journal":{"name":"2017 IEEE 26th International Symposium on Industrial Electronics (ISIE)","volume":"50 8 1","pages":"1023-1028"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83032646","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 support trajectory-based message delivery to moving vehicles, the driving locations of a vehicle need to be shared with message senders. However, from a security perspective, users want their driving locations not to be exposed to others except their desired senders for location privacy preservation. Therefore, in this paper, we propose a secure location-sharing system to allow a vehicle to share its driving trajectory with roadside units authorized by the vehicle. To design the proposed system, we put a central manager which maintains vehicles trajectory data and acts as a broker between vehicles and roadside units to share the trajectory data. Nevertheless, we make the trajectory data are hidden from not only unauthorized entities but also the central manager by making use of proxy re-encryption schemes. Hence, a vehicle can control that only the sender roadside unit designated by the vehicle can access the trajectory data of the vehicle.","PeriodicalId":6597,"journal":{"name":"2017 IEEE 26th International Symposium on Industrial Electronics (ISIE)","volume":"25 1","pages":"1451-1456"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81596506","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}
