Starting with some prior assumptions about stabilizability of the plants, a stable unsupervised architecture is obtained. It is a parallel distributed architecture, and it is shown that it provides bounded tracking and asymptotic regulation, following a class of teacher models. The feasibility of the method is demonstrated for a robotic manipulator.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117025744","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 robust stabilization problem for linear continuous systems is studied by means of a discrete-type Riccati equation, using the fact that the equation can be used analytically to place the closed-loop poles of linear continuous systems in a prescribed region. Hence, the design procedure is explicit and much simpler than previous methods. To ensure the physical realizability of feedback stabilization, an auxiliary control dynamics similar to the Luenberger state observer is introduced.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128223919","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}

An efficient procedure for Cholesky factorization of nonstationary covariances with such structure is presented. An inverse scattering interpretation of this procedure relates it to lossless cascade models with p+q-1 parameters per layer where (p, q) denotes the displacement inertia of the covariance matrix. Matrices with displacement inertia are of particular interest: they have given rise to cascade models that are lossless two-ports, with a single parameter per layer. The author uses the cascade model to construct Levinson-type recursions for the prediction polynomials associated with structured nonstationary covariances.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129702149","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 author exploits the normal equations of the least-squares method to establish that all stable control law designs used in a certainty-equivalent (i.e. indirect) procedure generally yield a stable adaptive control system. Four results that characterize the limiting behavior precisely are obtained. These general results are specialized to establish the convergence, asymptotic optimality, and self-tuning properties of a variety of proposed adaptive control schemes.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130509824","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}
