The key point of this research for nonlinear control is to develop a fist tracker with a flexible adaptive control scheme which does not require previous knowledge about the plant to be controlled, i.e., plant dynamic equations. Hence its algorithms have a flexibility for diverse applications. In order to carry out this research goal, system identification has successfully been achieved based on a recurrent neural network model, and nonlinear quadratic optimal law has also been derived and tested to the fast tracking problem for a robotic manipulator.","PeriodicalId":269440,"journal":{"name":"Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125016607","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}

Two significant advantages of using search coils to identify rotor position are: (1) the rotor position is always available; and (2) the effect of sensing current on output torque ripple is negligible due to the small current in the search coil. Initial experimental results indicate that the search coil technique does provide rotor position information with a resolution of approximately 0.6 mechanical degrees for an 8/6 design SRM.","PeriodicalId":269440,"journal":{"name":"Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125022421","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}

Sophisticated graphical interface software facilitates circuit assembly and simulator operation. Detailed power system component models together with flexible analogue and digital I/O enable detailed testing of power systems and external devices connected to such systems. The RTDS can be applied in various areas of power system study.
