The plant to be controlled is a 122-meter diameter, space-based, \"Hoop/Column\" antenna. The mathematical model, based on a finite element analysis, consists of three rigid-body rotational modes, and the first 10 elastic modes. A preliminary robust compensator design for achieving the required pointing performance is obtained using linear-quadratic-Gaussian (LQG) and loop transfer recovery (LTR) methods for loop-shaping. The computations are performed using the LQG design package \"ORACLS,\" and a recently developed singular value analysis package.","PeriodicalId":269680,"journal":{"name":"The 23rd IEEE Conference on Decision and Control","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125389992","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}

In truth, the results of mathematical management models are seldom used directly to formulate policy, but the policy regimes suggested by such models have been adopted by policymakers. An example of this dynamic is the evolution of harvesting policy decisions. Approximating a problem to provide a bound on the optimal policy can suggest the appropriate policy regimes without incurring the calculational burden of an exact solution. A fleet allocation problem demonstrates this technique.","PeriodicalId":269680,"journal":{"name":"The 23rd IEEE Conference on Decision and Control","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124649353","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 unifying purpose of these models is to impose sufficient conditions on the recursive defimtion of the objective function to guarantee the validity of the solution of the optimization problem by a dynamic programming iteration. In this paper we propose a general dynamic programming operator model that includes, but is not restricted to, optimization problems. Any functional satisfying a certain commutativity condition (which reduces to the principle of optimality in extrermzation problems see Section 2, B2) a-ith the generating operator of the objective recursive function, results in a sequential problem solvable by a dynamic programming iteration. Examples of sequential nonextremization problems fitting t h s framework are the derivation of marginal distributions in arbitrary probability spaces, iterative computation of stageseparated functions defined on general algebra~c systems such as additive commutative semi-groups with distributlve products, generation of symbolic transfer functions, and the Chapman-Kolmogorov equations.","PeriodicalId":269680,"journal":{"name":"The 23rd IEEE Conference on Decision and Control","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129464835","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}
