If the oscillation amplitude is beyond the shaft tolerance, it will lead to system insecurity problems. In this paper, the model of transmission mechanisms is firstly established, and based on that, four strategies: engineering design, pole placement method, shaft torque state feedback method and model predictive control are studied to suppress mechanical vibration and protect the safety of transmission. Simulation results show the advantages and disadvantages of the four strategies, meanwhile confirm MPC as the optimal method. MPC can suppress mechanical resonance, limit the amplitude of the shaft torque and allow the system to complete the transient process with maximum acceleration, taking dynamic performance and security into account at the same time.","PeriodicalId":228897,"journal":{"name":"IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129817623","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 DTC usually operates with a short sampling period, therefore estimation algorithms need to be computationally cheap. Moreover, injection of high-frequency (hf) signals into a given axis can be a challenging task in comparison with a standard vector control with a PWM modulator. In this paper, a modification of the DTC algorithm is proposed to enable hf injections in a separate d-axis in a rotating coordinate system. Demodulation of this signal and sensorless rotor position estimation based on both phase-locked loop and modified extended Kaiman filter are described and evaluated. Verification was performed by both simulations and experiments on a laboratory prototype of a PMSM drive with rated power of 11 kW.","PeriodicalId":228897,"journal":{"name":"IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128289274","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}

Therefore, a combination of several methods is necessary. Especially in the case of electrically excited synchronous machines, the methods proposed for the low speed region and for the detection of the initial rotor position fail for many types of machines and demand for new solutions. In this paper, a method for the identification of the initial rotor position by injecting low frequency pulses is proposed. After the identification of the initial position, the drive is directly started with the help of a conventional high-speed method and rides through the critical speed region without any difficulties. The new method is designed for a reliable operation in a large group of electrically excited synchronous machines. Measurement results as well as a concept for the parameterization of the model are included in this paper.","PeriodicalId":228897,"journal":{"name":"IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128979363","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}

Besides sophisticated chemical and physical methods for a direct material analysis, an indirect method based on information retrieval provides a less costly and more efficient alternative. During the process of information retrieval, PCBs and their components need to be recognized based on their appearance and the corresponding text information. Their material composition is then available through a pre-established database. Therefore, a practical text recognition is necessary for a successful data analysis prior to PCB recycling. Our paper is focusing on two key aspects of text recognition: binarization and final recognition of text objects using optical character recognition (OCR) engines. For binarization of text contents, a novel local thresholding method using an adaptive window size along with background estimation is presented. Several state-of-the-art algorithms and the proposed method were evaluated for comparing their binarization performance on text objects in PCB images. With respect to a data set containing manually created references, our novel method provides superior results. Furthermore, in contrast to previous work on text recognition, an additional evaluation of available open source OCR engines was conducted to asses technical limitations of OCR applications. We show that the quality of text recognition can be significantly improved if the binarization approach accounts for these technical limitations of OCR software. The presented method and results are expected to provide improved OCR performance also in other applications.","PeriodicalId":228897,"journal":{"name":"IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129349842","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 demagnetization of NdFeB magnets is quantified in terms of demagnetized magnet volume and loss of magnet remanence using finite element (FE) analysis. The impact of cross-coupled q-axis current and the rotor position are also investigated. The results comparing seven PM machine configurations show that burying the magnets inside the rotor using interior PM (IPM) rotor configurations generally improves the demagnetization performance. In addition, the machine configurations with distributed windings generally provides better demagnetization-withstand capabilities than the configurations with fractional-slot concentrated windings.","PeriodicalId":228897,"journal":{"name":"IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124627642","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 converter is similar to the LLC resonant converter with an extra inductor and capacitor in the secondary side. Soft-switching can be ensured in all switches without additional circuitry, and because of that, very high frequency operation is possible, hence; the size of the magnetics and the capacitors can be reduced. In this manuscript, first, an equivalent model for the bidirectional converter is derived for the steady-state analysis. Then, the design methodology is presented. Design of a converter includes finding the transformer turns ratio, design of magnetizing inductance based on ZVS condition, design of resonant inductances and resonant capacitances. To validate the design procedure, a 3.3 kW converter was designed following the guidelines in the proposed methodology as a design example. A prototype was built and tested in the lab. Experimental results verified the design procedure presented.","PeriodicalId":228897,"journal":{"name":"IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129422186","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}
