A novel method based on zoom-FFT has been developed, and compared to an existing method based on zero-crossing time (ZCT) processing using real data from faulty and healthy motors. Numerical tests show that both methods can reliably detect broken rotor bars. ZCT processing entails better performance than zoom-FFT for low load and low current, but zoom-FFT is easier to tune, thus being preferable for embedded systems such as motor controllers, soft starters and drives that have to operate with a vast variety of motors.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116618742","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}

High precision results can be obtained if the difference between the biosensor and a reference capacitance is estimated but this is difficult to be achieved if the range of the biosensor capacitance is wide. In this paper, a novel algorithm implemented in hardware that is used to configure an appropriate reference capacitance close to the biosensor value is presented. The resulting readout circuit is capable of accurately monitoring the changes of a biosensor capacitance, regardless of its initial value. More specifically, the reference capacitance is automatically configured to a value between 0 and 630pF in steps of 10pF. The proposed system can be used to measure an absolute biosensor capacitance of up to 640pF with 2.5fF sensitivity. The 2.5fF resolution is achieved by using a 12-bit ADC instead of a 18-bit ADC that would be required to measure the absolute biosensor capacitance value with the same accuracy. In this way, a lower area/power and higher accuracy readout system can be designed. Of course the capacitance ranges and resolution can be easily adapted to different application requirements.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129160643","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, we propose power assisting methods to suppress the velocity fluctuation similar to the repetitive control.

Smart grid evolution has, thus, a lot to gain through the exploitation of emerging Future Internet networking technologies for the efficient collection and management of the acquired information. The capabilities for interconnection of numerous intelligent networking devices, the advanced monitoring and control of dynamic networking infrastructures and the efficient handling of large volumes of data are research areas that have direct applicability into the smart grid design and operation. This article presents our insights for the design of a novel and open overlay networking architecture for leveraging end-to-end interconnection of physical or virtual objects, for achieving decentralized data management, and for providing distributed services in smart grid environments. The proposed architecture follows a layered-approach and extends or adapts a set of existing overlay and IP protocols.

This is due to the facts that plants grow in complexity and that modern automation systems are highly distributed and comprise complex components. To cope with these challenges and to guarantee short implementation times and a small number of errors for the automation systems, modern development processes are needed. Such modern processes can be reduced to four main aspects: (i) A seamless process with corresponding seamless tools, (ii) a high level of model reuse and adaptability, (iii) executable models and early tests, and (iv) a system-wide planing process of the distributed system. Therefore, the established tool landscape with its specialized tools for each discipline of engineering has difficulties to keep up with these trends. The approach presented in this paper implements a development process including the aspects (i) (iv) using the new data exchange format AutomationML. AutomationML serves as an enabling technology and has the potential to change future development processes and may trigger the development of new, better integrated tools.","PeriodicalId":365141,"journal":{"name":"2012 IEEE International Conference on Industrial Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128132390","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}
