In a stationary reference frame, the proposed control scheme keeps the α and β currents within given hysteresis bounds while minimizing the switching frequency of the inverter. Based on a internal model of the drive, the controller predicts the drive's future behavior for each switching sequence, extrapolates the output trajectories and selects the inverter switch position (voltage vector) that minimizes the switching frequency and keeps the predicted current trajectories within the hysteresis bounds. The scheme is applicable to a large class of (three-phase) ac electrical machines driven by inverters and it is also effective under all operating conditions, including transients and zero stator frequency operation. Specifically, the very fast transient response time of the classic hysteresis control scheme is inherited.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116482199","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}

Special attention is paid to acquisition of force-torque maps with respect to parameter sensitivity. Practical issues are pointed out and discussed in view of industrial applications. A quality assessment of force-torque maps based on a redundancy index is introduced hinting at the performance and possibilities of optimization of the assembly strategy.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125992878","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}

Electrical motors are more frequently used in variable-speed drives and thus their operation at resonant speeds has become a critical aspect, together with the increased audible noise and vibration. This poses a challenge for electrical machinery manufacturers in the form of demanding vibration and noise performance characteristics. This fact has to be taken into account in the electrical machine design process. The simulation of the electromagnetic sound power emission of an electrical machine is a three-stage process. First, the magnetic force waves in the air gap are calculated. Then a structure-dynamical model of the electrical machine is created. At this stage, the structural response, usually the vibration velocity is calculated for the magnetic excitation forces given. Finally, the radiated sound power is calculated. The traditional sound power simulation process is numerically heavy and time consuming and thus cannot be considered as an everyday or practical approach to electrical machine design. As a result, a new approach is required in order to carry out electromagnetic sound power calculation in a realistic time frame and with realistic effort. In this paper, a simplified methodology for computation of magnetic sound power based on unit-wave responses is presented, studied, and discussed.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128970212","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}

Since that the “intelligence” has emigrated to the point of measurement, a lot of efforts have been carried out to standardize the sensor connection. As an important result, the IEEE 1451 standards were developed. They allow automating this process by incorporating the necessary data as part of the transducer itself. One major benefit provided by the standardization process was the creation of a standard Transducer Electronic Data Sheet (TEDS) in IEEE 1451.2 This standard simplified the use of smart sensors by normalizing the way transducers can describe themselves to measurement and control systems. In the same way that the IEEE 1451 standard was created, signal parameters themselves should be standardized. An equivalent to the TEDS should be defined for the sensor signal feature extraction. A time domain algorithm is proposed as a building block for signal analysis. It is based on signal segmentation following of a labeling process. As a result, the smart sensor realizes what kind of signal it is sensoring. The computational cost of the proposed algorithms is extremely low so they can be built in into smart sensors and executed in real time to provide a normalized platform for sensory data cooperation.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131200011","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}
