This paper proposes an approach for overcoming this drawback of tight control by an AR model when it is impossible to carry out computer online control based on an autoregressive model. This approach in the broad sense of the term involves robust control in which model-based deep knowledge based on an existing AR model or mathematical model is used and converted to fuzzy qualitative oontrol. As an actual example we discuss a cement rotary kiln process, and we present an approach for process disturbances and incomplete measured values by transforming quantitative control into qualitative control and also making use of hidden information that cannot be abstracted without sensor fusion. As a feature of this method we discuss the effectiveness and purpose of the paradigm in which one does not quantify a qualitative model but rather goes in the opposite direction of qualitizing a quantitative model.</p></div>","PeriodicalId":100097,"journal":{"name":"Annual Review in Automatic Programming","volume":"17 ","pages":"Pages 353-358"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0066-4138(09)91058-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116865267","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 technique for compensating the residual is proposed. By compensation, the effects of modelling errors on the residual will not adversely affect the detection and isolation of faults. The idea is to estimate approximately the bias term in the residuals due to modelling errors, then compensate it on-line. These estimates are used to form a compensated residual to decrease the effect of modelling errors on the residuals. The compensated residuals are then used to make the fault diagnosis decision. Simulation results illustrate the effect of incipient faults in sensors of a complex jet engine can be reliably detected with the method developed.</p></div>","PeriodicalId":100097,"journal":{"name":"Annual Review in Automatic Programming","volume":"17 ","pages":"Pages 221-227"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0066-4138(09)91037-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115686938","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}

However, more important for practical real time applications is the direct processing of the knowledge contained in a decision table by combining concept analysis with Shannon's entropy.
