Based on these definitions, algorithms are derived to calculate and reduce the index. Pantelides (1988) has used the differential index to construct his well known algorithm. We propose to use the perturbation index. This naturally leads to finding the highest power of s of each element in (As+B)/sup /spl minus/1/. These highest powers determine the perturbation index of DAE Ax'+Bx=f(t). With fast graph-oriented algorithms this highest power can be found and, consequently, the perturbation index can be determined.<<ETX>>","PeriodicalId":197997,"journal":{"name":"Proceedings of IEEE Symposium on Computer-Aided Control Systems Design (CACSD)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125084804","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 is based solely on input-output data from the process, and the user does not necessarily have to make any design decisions. The first step of the design procedure is the identification of a process model and the estimation of its uncertainty. In the second step a controller is designed based on this model. The controller is fine tuned in such a way that robust stability is guaranteed when the estimated uncertainty from the first step is taken into account. The software for both steps is written in Matlab. The paper first describes the basic principles and tools of the design procedure. Then the software implementation is described. The last two sections contain examples and conclusions.<<ETX>>","PeriodicalId":197997,"journal":{"name":"Proceedings of IEEE Symposium on Computer-Aided Control Systems Design (CACSD)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125148897","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}

Typical examples are the so-called mechatronic systems. These are systems whose basic structure is usually a mechanical one with mostly higher transmission bandwidth and which are completed by actuators and sensors for a better statical and dynamical behaviour. Their special efficiency is due to a combination with information-processing systems; these are usually digital control elements. The considerable complexity of systems of this kind requires systematization of the design process, as regards model generation, system analysis and synthesis. This, however, is indissolubly linked to software support covering the entire design cycle. This is the starting point for my contribution which will present a uniform system description language for various technical disciplines. It is the basis of a graphics-oriented, interactive design environment for developing and realizing mechatronic systems which will be exemplified in detail by their modelling and nonlinear simulation.<<ETX>>","PeriodicalId":197997,"journal":{"name":"Proceedings of IEEE Symposium on Computer-Aided Control Systems Design (CACSD)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122059038","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}

Beside an internal toolset for linear analysis, nonlinear simulation and optimization based on the system description language DSL, CAMeL has the possibility to use other, i.e. commercial design environments to enhance its performance. In addition, CAMeL software processes are able to communicate online with technical processes. Thus design and optimization of controllers can be performed directly in the real plant.<<ETX>>","PeriodicalId":197997,"journal":{"name":"Proceedings of IEEE Symposium on Computer-Aided Control Systems Design (CACSD)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132814045","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}
