These data show that overall device switching performance is not improved for low temperature operation and is degraded at temperatures above room temperature.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132288596","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}

Both coarse and fine control with the help of lookup rule tables are used to improve transient response and system settling time. The performance characteristics are compared with those of proportional-integral control. Simulation results clearly indicate the superiority of fuzzy control with a larger numer of rules. The fuzzy controller was implemented with a 16 b microcontroller and tested in a laboratory on a 3 hp insulated-gate bipolar transistor (IGBT) inverter induction motor drive system. The test results verify the simulated performance.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131441930","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}

A charge coupled device (CCD) line sensor was used to detect the object pattern, and a DSP (TMS32025) performed the spatial filtering calculations. Because the selectivity of the spatial filter was fixed, the measurement accuracy of this approach is generally influenced by the condition of the object pattern. A method that improves the accuracy of the velocity measurement by using two pairs of spatial filters with phases orthogonal spatial weighing functions was developed. The new method of velocity measurement is described with some experimental results.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128359156","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}

A fast reduced-order observer is shown to be most suitable for sliding mode speed control applications.

This very simplified approach is shown still to have validity in both stepping and SRM design, but caution is needed. The different design recommendations are critically examined and compared with results from full computer models, validated by extensive comparisons with measured behavior from prototype and commercial machines. Different criteria for optimization are used in a practical design study, including loss constraints. Torque optimization without loss constraints produces maxima which accord well with the figure of merit correctly based on a nonlinear magnetization curve. An important aspect of this study is the introduction of corrections for core loss, based on an empirical formula.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134415549","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 transducer uses the synchronous machine terminal voltage and current to calculate the machine internal voltage and its frequency, which is proportional to shaft speed. Unlike the more usual shaft-mounted transducers, this transducer has no mechanical interface with the machine. Therefore the errors introduced by machine shaft vibrations, temperature changes, and other factors are virtually eliminated. The transducer was implemented using an Intel 80C196 single-chip microcontroller together with the supporting analog and digital transducers. The results of various tests of the transducer accuracy, together with the transducer main hardware and software design features, are presented and discussed.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121052455","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}
