A first order model with deadtime forms the basis of the well-known compensation scheme which is used in combination with a main process controller of the proportional plus integral (PI) form. Here, adaptation of the static model gain is added in an attempt to stabilize the control system in the face of certain types of process changes. This gain-adaptor also uses PI control of the static model gain to force the undelayed model response into agreement with the process response. Further, as the static model gain changes, the main process controller gain is changed in an attempt to maintain stability. Test runs were made on an actual double-pipe heat exchanger of an industrial size using steam to heat water. Control of the outlet water temperature (process response) was tried using the deadtime compensation schemes and regular PI control by itself. The responses for step changes in set-point water temperature show the superior tracking behavior of the deadtime compensation schemes. For decreases in the water flow rate, it is shown that regular PI control and Smith's method can give oscillatory responses. With proper tuning the gain-adaptive procedure is shown to maintain stability for this type of process change.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"25 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":"115186167","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}

In the block-1, a set of observed signals is identified with one of the categories prescribed to present the normal and several anomalous situations in multidimentional space, where the linear discriminant functions basing maximum likelihood technique are utilized. An approximate linear dynamic model for the individual prescribed anomalous state is identified beforehand, where the disturbance and several assumed variables are utilized in a dynamic model and a observed vector is composed of several selected observed signals. The Kalman filters for all anomalous categories are obtained using corresponding dynamic models, and they are provided in the block-2. When the present state is identified to one of the prescribed anomalous situations by the block-1, a Kalman filter corresponding to the identified category is selected from the block-2, and the disturbance is estimated using the past observed signals obtained from the block-3 and future coming signals. The linear discriminate functions and the approximate linear dynamic models are derived using the data base of prescribed categories obtained from the accurate plant simulator. The database will be improved by the experience of actual plant. The effectiveness of this diagnostic system was examined by the computer experiment. The results show that classification of the present operating state and estimation of disturbance are available with reasonable reliability and reasonable computation time.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"29 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":"114228558","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}
