This controller resembles a parameter adaptive controller while it is in the tuning phase. When it is not tuning it functions like a closed-loop PID controller. The model used to represent the diesel engine contains nonlinearities and widely ranging parameters. Computer simulations were used to verify that the tuned system's phase and gain margins meet design requirements.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130584765","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 vehicle control that has enabled an autonomous vehicle to travel at speeds up to 35 km/h is discussed. The limitations of existing schemes that restrict their consideration to kinematic models are pointed out, and it is shown that it is possible to obtain an increase in performance through the use of approximate dynamical models that capture first-order effects. The present approach combines such a modeling philosophy with accurate feedback in world coordinates from sensors that have only recently become available. Experimental results of an implementation are presented.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130194258","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 method involves performing the discrete Hartley transform (DHT) by way of a simple vector-matrix multiplication with an incoherent optical processor. The DFT is directly obtainable from the DHT and vice-versa. However, the Hartley transform of a real function is real. The kernel of the Hartley transform is real, which makes it more suitable for application in an incoherent optical processor than the complex Fourier kernel. High-speed spectral estimation of sinusoidal radar for electronic warfare purposes is a potential application. Experimental results that demonstrate the method are presented.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130918364","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}

Fuzzy logic is used to model heuristic knowledge. Nonlinear stability criteria are applied to guarantee the stability of the control of the control system. The analysis and design of the intelligent control system is carried out by means of the conicity stability criterion. By using this criterion it is possible to find and modify the critical rules influencing stability. A Scara robot is considered, and the robustness of a fuzzy controller is shown. The results can be easily extended when using other techniques to model the heuristic adaptive and learning control schemes.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123707519","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 extended influence function (EIF) has been proposed to study the effect of large proportions of outliers on an estimator's value. This extends the definition of the influence function which is mainly an infinitesimal tool. It is shown that the EIF may be used to predict qualitatively, useful performance measures like the output mean and the mean-square error. Specifically, the EIF is used to investigate the performance of the modified trimmed mean filter. Performance predictions are compared with results obtained through statistical simulations.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128543596","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}
