Concepts like Carleman linearization, multivariable Laplace transform, and semi-lattice are discussed to prepare for the main theorem which characterizes the degree of minimal realization in terms of the minimal generators of the exceptional points. The results here lay the foundation for further work in the realization problem of stationary linear analytic systems. These ideas also have potential application to nonlinear identification and parameter estimation problems.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"41 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":"126120427","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}

Design of reduced-order linear quadratic optimal regulators 降阶线性二次型最优调节器的设计
G. Langholz, U. Shaked
{"title":"Design of reduced-order linear quadratic optimal regulators","authors":"G. Langholz, U. Shaked","doi":"10.1109/CDC.1980.271806","DOIUrl":"https://doi.org/10.1109/CDC.1980.271806","url":null,"abstract":"It is perhaps possible to distinguish between two main approaches to problem of model reduction [1]. The first uses open-loop criteria (not necessarily optimal) for producing low-order models [2,3], while in the second, criteria which are optimal in some sense are employed. The latter approach can too be divided into two subgroups. In the first, error criteria are used to optimally approximate the open-loop behaviour of the original system [4,5]. In the second, either a given low-order model is optimally controlled and the resultant controller is used to (sub-optimally) control the original system [6]; or, a low-order model, whose dimension equals the number of outputs of the original system, is designed such that the error between the optimally controlled model and original system is minimized [7]. A completely different approach is considered in this paper. For a desired model order, the model is designed such that, controlling it by a constant state-variable feedback and using the resulting input to control the original system, the performance index of the original system, is minimized. Therefore, we are not contrained a priori by the model order (as in [7] for example, where a single-output original system necessarily results in a first order model). Furthermore, the performance index of the original system itself is being minimized under the constraint of the desired order model. Notice, however, that the proposed solution could not be considered open-loop in some sense and thus, could not be used for designing low-order models for unstable systems.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"94 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":"124744314","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}

It is shown how the error model can be described by a non-homogeneous differential equation. Subject to bounded disturbance and parameter variation and sufficiently rich input the parameter error vector remains bounded and explicit bounds are derived. For inputs that are not sufficiently rich some sufficient conditions for stability and some examples of instability are given. Finally, a non-linear adaptation algorithm is presented for the control problem that insures the boundedness of the parameter error vector and all signals in the system.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"4 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":"129237712","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 analysis, design, and implementation of this system should be of interest not only as a control application, but also because it brings out some important features which are generic to the positioning of tendon arms of all types. Most particularly, a crude but effective form of load compensation is shown to be possible without (the equivalent of) proprioceptive feedback; this supports recent physiological findings which suggest that large arm movements in primates may be predominantly open-loop processes of final position control.","PeriodicalId":332964,"journal":{"name":"1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"16 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":"121058817","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}
