We develop a mathematical model for estimating the influence of technical parameters such as the mean cell residence time, water and sludge recycle rate and possible intermediate feed or the influence of process configuration such as number mode, relation of size and interconnection of reactors. The model is based on the IAWRQ model No.1, and it describes the microkinetics of enhanced biological phosphorus elimination in addition to the degradation kinetics of carbonaceous components and nitrogen. The data from dynamic investigations such as daily patterns in flow and concentration shock loads or faults were compared with the predictions made by the dynamic model. An outline for the application of the developed complex model to waste water treatment plant is discussed.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114447037","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 discussion includes a brief look at the advantages of using DSPs in real-time control applications and the techniques of integrating DSPs with parallel processing transputer networks to enhance computing power. The main focus of this paper is the design of a system that combines the excellent real-time response of the Texas Instruments TMS320C30 DSP with the superior computational power of a parallel processing system based on Intel i860 RISC processors and Inmos transputers. The software of the system is hosted in the popular MATLAB environment to provide a simple user interface as well as many powerful mathematical tools. The system also includes a simulation package to allow rapid verification of the user's program and control algorithm. The system is ideal for implementing advanced motion control experiments requiring high speed floating point computations and fast sampling rates. A complex adaptive motor control experiment is presented in this paper to illustrate the use of the system.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"203 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115026483","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 linear model is identified from a nonlinear digester model, which is obtained by applying the method of orthogonal collocation to a model in terms of partial differential equations. The linear model is used for control design employing the Smith predictor in combination with an H/sub /spl infin// robust stabilization procedure. Simulations using both the nominal and perturbed nonlinear models in combination with both a full and a reduced order controller are performed. Simulation studies show that the proposed control design approach is useful and may prove effective in digester control.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117300505","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 starts from one available approach that evaluates the control performance compared to minimum variance control. The authors show, using an example and also from industrial data, that this technique gives an inadequate measure of the performance if the aim is not stochastic control, but step disturbance rejection. Therefore, some modified criteria are proposed and a monitoring tool utilising all available techniques outlined.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124721598","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 the development of these control concepts physical understanding of the process dynamics is needed. Therefore, a thermodynamic model is used to study the dynamic properties of the cold store, with emphasis on the coupling of temperature and relative humidity. With this knowledge, together with the heuristic knowledge of refrigeration engineers, rule-based control strategies for refrigeration systems are proposed. For the implementation the fuzzy logic method is used. The design with fuzzy logic allows one to take into account the complex coupling of the dynamic variables temperature and humidity in a straightforward manner. A survey of the control structure and simulation results are presented. It is shown that the fuzzy controller gives favourable process behaviour, e.g. under the influence of disturbances or after changes of set points.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128381729","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}
