Due to the change of rail track and running speed, both slip and operating traction force keep changing. Therefore, there is a requirement of reliable identification of wheel-rail contact force properties and adhesion level for acceleration or braking controls to adapt to different track conditions. Since wheel slip controller shows many applications in the aspect of safety relevant features, such as slip control, emergency brake assistance, locomotive operation, etc. the proper estimation of traction force and the detection of maximum traction force between rail and wheels are very important factors in the railway industry. Furthermore, an advanced scheme with traction drive control is required to achieve the maximum adhesion level for a railway vehicle. This paper proposes a new identification technique scheme which is designed to regulate the torque reference according to the maximum traction force. The proposed scheme is built with Recursive Least Square (RLS) scheme to identify the peak slip level at maximum traction force with the searching technique based on the traction force estimated by a Kalman Filter. Furthermore, this scheme is also used to operate the traction system within the identified maximum traction force region. Simulation model validates that the proposed controller with identification scheme can control the train or locomotive to obtain its maximum adhesion force.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130412880","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 order to meet this need, the behavior of the prime mover can be emulated by an electric machine energized and controlled by a power electronic motor drive. The prime mover can be various mechanical power sources such as gas turbine, diesel engine and wind turbine, etc. In this research, we focus on using controlled alternative-current (AC) electric machines, i. e. induction machines and synchronous machines, to emulate prime movers. Based on linearization and power balance, an equation is derived to specify the matching of motor drive and electric machine in prime mover emulators (PMEs). This equation helps the selection of a motor drive and an electric machine in appropriate pair for a prime mover to be emulated. It also helps the design of test items for PMEs. The effectiveness of the matching equation has been verified by simulation tests in Matlab/Simulink.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127991544","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 order to harvest the maximum power from implanted rectenna, power management system is needed. However, most of power management systems are not efficient due to power consumption in control circuitry. This paper presents a fabricated rectenna with 63% power efficiency and an optimized power management circuit to improve the efficiency of DC-DC converter, where the rectenna is used as power source, this is accomplished by using particle swarm optimization technique. This design improves the efficiency of optimized power management circuit by 10% comparing with conventional power management circuits over a wide range of input power, allowing harvesting more power from rectenna and delivering it to medical device; it can extend the battery life of implantable medical devices.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132814142","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}

IPMSMs (flat plate type, V-shaped type, spoke type) are investigated by finite element analysis (FEA) using the same volume of the permanent magnet while changing the magnet's width, and thickness and magnetic field orientation angle. FEA found that a V angle of 130° and a changed magnet length of 107% (or V angle of 100° and a changed magnet length of 97%) using an oblique magnetic-field-oriented magnet strike a good balance between demagnetization resistance and torque at 180°C. In the V-shaped arrangement, for a motor with the same magnet length, the demagnetization resistance at a magnetic field orientation angle α = 20° is better than that at α = 0°. The magnetic field orientation angle α = 20° has a magnetic flux density distribution closer to a sinusoidal wave form than α = 0° and is thus effective for reducing torque ripple.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"9 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134293780","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 implies that the implementation of predictive control techniques in this converter requires high computational cost while an adequate selection of weighting factors in order to control both input and output sides. In addition, the technique presents a variable switching frequency which could produce resonances in the input filter damaging the performance of the system. In this paper, two indirect model predictive current control strategies are proposed in order to simplify the computational cost while avoiding the use of weighting factors. The first method consists in a predictive current control strategy with minimization of the reactive power minimization enhanced with an active damping implementation which allows mitigate resonances in the input side. The second proposal consist in an indirect model predictive current control with imposed sinusoidal source currents in the input side. Simulated results confirm the feasibility of the proposals demonstrating that with both alternatives it is possible to mitigate the resonances on the input filter.","PeriodicalId":411916,"journal":{"name":"2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115076106","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}
