Because of the large fluctuations in load, a fixed algorithm in the conventional area controller has some serious disadvantages. In the paper model reference adaptive control (MRAS) is applied in order to deal with variations in the parameter which relates the variations in the frequency to variations in the load. Adaptive control and conventional control are compared. Further improvements have been realized by changing the structure of the conventional power frequency control algorithm and by introducing a feed forward adaptive action. In the simulation numerical values of the power stations in Amsterdam (GEP) and Zeeland (PZEM), which operate within the tie-line system in the Netherlands, have been used.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128978323","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}

This additional attribute data can be employed in associating a given report with a set of previous reports in the data base (track) thought to represent a single object. The present Bayesian analysis of the association probabilities, arising from such attribute data goes beyond previous treatments in three ways. First, explicit allowance is made for four different types of attribute parameters encountered in many multi-sensor systems. The second distinguishing feature of this scheme is the explicit consideration of uncertainties in report parameters due to errors and deception, and of uncertainties in track parameters due both to these causes and to association probabilities less than unity. Finally, an inference procedure, based on conditional prior probabilities, is developed to treat cases where there is limited overlap between report and track attribute sets. This situation is frequently encountered in multi-sensor systems.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131006382","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}

Nevertheless, control (observation) spillover may be prevented by proper placement of actuators (sensors). If proper placement is not possible because of structural constraints, control spillover to (observation spillover from) secondary modes can still be prevented by synthesizing the existent actuator (sensor) influences. Alternatively, control spillover to (observation spillover from) nonprimary modes can be reduced, to various extent, by adding some bandstop filter to each input (output) channel. A combined systematic use of placement, synthesis, and filtering will yield better results. This paper presents the underlying theoretical foundation of a proposed three-step approach for alleviating the spillover problems, along with conditions and techniques for proper placement, proper synthesis, and proper filtering. An illustrative numerical example is also included.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":" 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114051186","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}
