A set of generic elements are interconnected by generalized junction structures to represent a variety of system configurations. The response of pressure, flow, temperature and heat transfer rate at any point or station in a system is then determined due to a wide range of fluid, thermal and mechanical disturbances. The model has been used to analyze furnace implosions in fossil fuel power plants. A coal-fired plant model has been constructed and simulated. The model simulations of the furnace pressure excursions are in close agreement with the data from the field tests.","PeriodicalId":236856,"journal":{"name":"1985 American Control Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115960084","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 nonlinear engine dynamics are linearized at nine distinct operating conditions. Scaling of variable units and Singular Value Decomposition at DC identified the subset of controls and outputs for dynamic control. At each operating condition an LQG/LTR compensator is designed; the parameters of the LQG/LTR compensator are then scheduled to produce a global dynamic compensator. Transient simulations are included to illustrate the characteristics of the nonlinear multivariable control system.","PeriodicalId":236856,"journal":{"name":"1985 American Control Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115370077","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}

If the control variables do not enter the objective function, it is found that the instantaneous optimal conditions are found where the product of the sensitivity matrix of the state variables to the control and the gradient of the objective function in the state space is zero. In some cases, this means that the process state is insensitive to the control at the optimum, which makes traditional proportional control instable. Therefore, the modeling and parameter estimation for process non-linearities to identify an optimum become essential. The control problem becomes a tracking problem. This paper describes the application of those ideas to a simple continuous stirred tank reactor with multi-component and multi-reaction kinetics.","PeriodicalId":236856,"journal":{"name":"1985 American Control Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115466910","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}

For processes with large thermal capacitances, it is especially difficult to avoid overshoot during startup unless a very conservative (i.e., slow) startup is implemented. Adaptive control strategies are a promising solution because they can be used to predict the time at which heating should be stopped and cooling begun. Simulation studies for a fluidized sandbath demonstrate the advantages of the proposed approach.","PeriodicalId":236856,"journal":{"name":"1985 American Control Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116707379","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}

This paper continues previous efforts in establishing a systematic approach to the combination of both types of information using membership functions based upon multiple-valued logic. Filters are established for literal and non-numerical attributes, somewhat analogous to the well-known Kalman filter. The major result, however, is an improvement and clarification of a previous theorem establishing asymptotic forms for the posterior possibility distribution of the unknown data association parameter as information granularity decreases and as inference rule structures become more definitive.","PeriodicalId":236856,"journal":{"name":"1985 American Control Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121255181","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}
