Using training experiments with 3-D parking profiles extracted from a sequence of images, the vehicle learns and generalizes its behavior, when recognizing free parking slots and manoeuvering inside a parking slot. Using a modular set of functions, implemented by neural networks trained in simulated environments, the vehicle accomplishes parking tasks in various parking situations.<<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":"115625334","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 state vector is composed of the biomass -X- and two substrates, an intracellular one -Sin- and an extracellular one -So-. It is estimated by an online measurement of the oxygen uptake rate. As the problem is too complex to be solved by a single stable observer, the estimation problem is divided in three subproblems, solved by estimation algorithms proved to be convergent. These algorithms use a minimal modelling of the process. It provides the estimation of the whole state and of two kinetic parameters, the specific biomass growth rate and the absorption rate of the substrate by the cells, considering the general equations of the dynamical model and the mass balance of the substrate in the bioreactor. This paper presents the design of the estimation algorithms and discusses their results in simulation and on experimental data from a pilot plan.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"9 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":"123094095","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 design process takes account of both random and deterministic track inputs, and shows that the controllers which are produced by a LQG approach do not in general give a satisfactory response for deterministic inputs. The performance for a number of state space formulations is evaluated, and compared in the context of the suspension design requirements. Two of the formulations include the effect of integral control to reduce the low frequency errors and improve the response to deterministic inputs.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"42 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":"125140702","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 transformation is based on the description of the heredity of the system through an additional state variable and thereby allows the solution of the quadratic optimal control problem to be simply determined. Some numerical simulations are provided also with the aim of demonstrating the legitimacy of the approach in the experimental field.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"49 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":"126763008","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}

Partial state feedback control, which uses measurable states besides outputs, has the advantage that the number of pole/zero cancellations can be reduced.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"18 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":"115093911","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 article presents a software structure, which gives additional possibilities to create modular, distributable, asynchronous software components, and where updates are easier and can be done online.

In the pilot-plant of GBF we use a controller area network (CAN) based field-bus network to interconnect the decentralized process control computers under real-time conditions. In this paper the implementation and the performance of the CAN field-bus in an hierarchical automation concept is outlined. While some fermenters and downstream devices are connected to the network directly via an A/D converter and bus access in a so-called mini-module, other fermenters are automated with decentralized process computers which act as bus nodes with full functionality. A master computer interconnects several sub-nets and supervises the proper operating of all network components. In addition, a database is handled from this master, where all objects in the network, representing measured, controlled or online calculated variables, are specified. The CAN application layer enables an open communication from CAN-modules of different manufacturers. The CAN-message-specification allows the description of the data transfer between the individual user programs via a client/server model.<<ETX>>","PeriodicalId":173370,"journal":{"name":"1994 Proceedings of IEEE International Conference on Control and Applications","volume":"8 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":"114604028","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}
