These basis functions induce the so called Hambo transform, which transforms scalar systems into square systems of i/o dimension equal to the order of the all-pass function considered. We will consider the construction of the Markov parameters of the system representation in the transform domain and show how these can be used to realize minimal state space representations for the exact and partial knowledge case. Additionally a projection mechanism is presented to allow inverse transformation of any sequence of Markov parameters in the transform domain. This mechanism is illustrated with an example.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"3 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":"128446386","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}

On-line process monitoring and operator advisory systems support early detection of causes for sub-optimal plant operation and thus help to reduce fuel cost. Remote access to plant data makes it possible for plant owners and service providers dealing with geographically widely distributed assets to keep labor cost low by deploying specialists among multiple sites from one single location. Plant and Enterprise Management will profit from the integration of data from process-oriented systems (process control, performance monitoring, maintenance management etc.) with business systems (financial tracking, load scheduling, energy trading, etc.) and will thus be able to secure competitive advantages by quickly reacting to changing market needs based on up-to-the-minute information on, e.g. fuel cost, availability, load forecasts.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"1 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":"129977050","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}

Such model consists of static nonlinear part and linear dynamic part in a cascading structure. The static nonlinear part is modeled by a fuzzy neural network (FNN), and the linear dynamic part is modeled by an auto-regressive moving average (ARMA) model. Based on our approach, a nonlinear dynamical system can be divided into two parts, a nonlinear static function and an ARMA model. Furthermore, a simple learning algorithm is developed for obtaining the parameters of FNN and ARMA model. In addition, the convergence analysis for the cascade model (FNN+ARMA) is also studied by the Lyapunov approach. A simulation result is given to illustrate the effectiveness of the proposed method. Simulation result also demonstrates that this approach is useful for systems with disturbance input.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"136 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":"128987035","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}

And in this sense this kind of \"backward\" anti-windup should always be used because it is never possible to prejudge of any non-linearity that could appear. However, when an a priori knowledge of some non-linearities are known, it is possible to include this knowledge either in the synthesis of the control or in the conception of a \"forward\" anti-windup. Two examples of forward anti-windups are given in the paper, namely the optimal conditioning and the predictive conditioning techniques.","PeriodicalId":117668,"journal":{"name":"1999 European Control Conference (ECC)","volume":"9 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":"131025952","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}
