The matrix Nevanlinna-Pick interpolation theory is applied to give a necessary and sufficient condition for the existence of a sensitivity matrix meeting the upper bound conditions on the j¿-axis, and the matrix Nevanlinna-Pick algorithm is used to compute the bounds. A scalar example is also presented to demonstrate the trade-offs between the bounds inside and outside a given operating frequency band.","PeriodicalId":269680,"journal":{"name":"The 23rd IEEE Conference on Decision and Control","volume":"52 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":"124361687","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 this paper, we are concerned with the subset Sn,l of Sn, consisting in systems whose cyclic structure is l. It is first stated to be a submanifold of Sn, and an atlas is given for it. When l ranges over all cyclic structures, (Sn,l) is a partition of Sn, one element of which is open (and dense), namely the submanifold of cyclic systems. We then introduce special factorizations for transfer functions, which allow us to give another parametrization for Sn,l, in particular, transfer functions of cyclic systems admit a rather simple description. As this paper is a shortened version of [2], most proofs are omitted.","PeriodicalId":269680,"journal":{"name":"The 23rd IEEE Conference on Decision and Control","volume":"22 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":"121943246","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 integrand is \"weakly coercive\", which leads us, using the dynamic programming method, to characterize the optimal cost among the solutions of the solving equation, with radiative conditions expessing the centripetal aspect of the optimal control. The evolution of the problem when the discount vanishes is then considered: the integrand being \"strongly coercive\" (i.e. its gradient being outward), a limit problem is defined and similarly solved; an inward optimal control exists, which is the limit of the ones of the initial problems. The existence properties are obtained by means of a priori estimates concerning suitable solutions of the solving equations in the whole space.","PeriodicalId":269680,"journal":{"name":"The 23rd IEEE Conference on Decision and Control","volume":"21 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":"121729681","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}

Both the Nyquist and inverse Nyquist type of norm-bounded criteria are considered. The extended criteria form the theoretical basis in the formulation of an iterative procedure for searching the regions of stability for simultaneous gain or phase variations in multivariable feedback systems. The basic idea of the iterative procedure lies in successively perturbing the feedback system from a set of nominal gains or phases that are on the boundary of a previously established region of stability. The iterative procedure is illustrated by a numerical example.","PeriodicalId":269680,"journal":{"name":"The 23rd IEEE Conference on Decision and Control","volume":"1 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":"131349901","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}
