It describes the difficulties of obtaining a sampled data measurement that is free from aliased components and goes on to describe different methods of measurement and how they can be matched to the spectrum of the web product. It outlines how an understanding of the spectral properties of scanned data can lead to the reconstruction of two dimensional data profile in a way which is superior to current practice. The paper concludes with a description of a special machine developed to test and compare different methods of establishing cross direction pro-files.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132964576","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 new error model is developed for design of an adaptive variable structure controller using only input-output measurements. In this approach, a neural network universal approximator is included to furnish an on-line estimate of a function of the state and some signals relevant to the desired trajectory. It is shown via Lyapunov stability theory that the asymptotic tracking accuracy of the closed-loop system can be arbitrarily improved by decreasing a positive design parameter r, whose inverse characterizes the bandwidth of a so-called averaging filter.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"25 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131239009","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 electrical drives are characterized by standard models for which even the classical (linear) control structures give satisfaction [ast95]. The design relations result on the basis of the fact that fuzzy controllers can be, in some certain conditions, well approximated by linear controllers and, so, the Extended Symmetrical Optimum method [pre96] is applicable in this situation. A detailed analysis based on digital simulation results proves that the proposed fuzzy controllers can ensure better control system performance with respect to the reference input in comparison with other structures containing conventional controllers.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130967695","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}

After overviewing optimisation problems in Manufacturing Systems, it presents the integration of existing tools for the modelling and evaluation with Petri nets and a general-purpose optimisation package based on Simulated Annealing.
