The proposed approach is based on decoupling the stator current vector into both colinear and orthogonal components to the rotor flux vector. These components are the scalar and vector products of some parameters and rotor flux vector. The control problem where new parameters are control inputs is considered. The problems of designing the torque, speed and rotor position controllers are investigated.<<ETX>>","PeriodicalId":267349,"journal":{"name":"ISIE '93 - Budapest: IEEE International Symposium on Industrial Electronics Conference Proceedings","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124153682","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 the manipulator is a time-varying system, because of changing of the load and the friction between the joints the proposed MIMO model parameters are updated recursively online by the least squares (RLS) algorithm. A self-tuning type predictive controller is then designed by minimizing a quadratic performance criterion which includes the position error of the gripper and the energy associated with the torque vector, to control the position of the end-effector. The performance of the predictive controller is tested under varying operating conditions by digital simulation studies.<<ETX>>","PeriodicalId":267349,"journal":{"name":"ISIE '93 - Budapest: IEEE International Symposium on Industrial Electronics Conference Proceedings","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114340374","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}

One of them is the analysis of energy consumed during transients. An energy optimizing theory is developed, and its practical implementation is proposed. The other is the effect of the speed sampling lag time during transients, which can totally destroy indirect field orientation. An adaptive algorithm is developed to compensate its effect by estimating the real speed. The theory is confirmed by measurements. The implemented drive is fully digitalized, the algorithms are supported by the TMS32010 digital signal processor (DSP).<<ETX>>","PeriodicalId":267349,"journal":{"name":"ISIE '93 - Budapest: IEEE International Symposium on Industrial Electronics Conference Proceedings","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114804475","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}

Validation tests show good performance, hence increasing confidence in these methods. Monthly mean squared errors remaining after adjustment are presented and compared with those of deterministic methods, since these are other options for the estimation problem. A possible caveat of artificial neural networks (ANN) is that they are very difficult to interpret. Interpretation of the learnt representation in this case is offered by simulating with selected inputs, showing reasonable results and providing some insight in the hydrologic process being modeled. This is a generic possibility for dealing with black-box models. When estimating some system's behavior it is interesting to know whether the qualitative representation is also faithful. In the proposed example, special properties of the flow series with significance in hydrology, such as ranges, are obtained and compared with the sample values, along with other statistical features.<<ETX>>","PeriodicalId":267349,"journal":{"name":"ISIE '93 - Budapest: IEEE International Symposium on Industrial Electronics Conference Proceedings","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488668","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 objective of the research is to provide a reliable grading tool to the industry which will give a uniform grading standard across the country. In addition it is intended to increase throughput and provide quantification of the variation in tobacco leaf quality. The heart of the automatic grading system is a high-speed online image processing system developed to process images at a field rate of 50 Hz. The image processing is performed by Texas Instruments TMS 320-E-25 microprocessors operating in a parallel configuration.<<ETX>>","PeriodicalId":267349,"journal":{"name":"ISIE '93 - Budapest: IEEE International Symposium on Industrial Electronics Conference Proceedings","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127054056","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 novel structure for multilevel control is proposed. Single phase systems operate mainly as a force commutated rectifier however line commutation is very useful especially for zero crossing supply voltage because, during overlapping, current rate is high and harmonics are reduced. In a three phase system the multilevel control is achieved by using 9 active switches. A method based on a comparison reference and available current rates or comparison voltage drops on supply side inductances is proposed to evaluate the rectifier controllability. Results of simulation and laboratory tests confirm a unity power factor.<<ETX>>","PeriodicalId":267349,"journal":{"name":"ISIE '93 - Budapest: IEEE International Symposium on Industrial Electronics Conference Proceedings","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132875460","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}
