Since Q/sub D/ is the set dual to the rectangle Q/sub R/ considered by V.L. Kharitonov (1978), the result obtained is called the dual theorem of Kharitonov. This theorem shows that a family of polynomials with coefficients q varying in the diamond Q/sub D/ is strictly Hurwitz if and only if eight one-dimensional edges of the diamond are strictly Hurwitz.<<ETX>>","PeriodicalId":113534,"journal":{"name":"Proceedings of the 27th IEEE Conference on Decision and Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129623474","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}

Earlier results linking minimum-sensitivity realizations for linear time-invariant systems to the balanced realizations are extended to the multimode and general time-varying systems. The main design problems are posed in a geometric framework, and the geometric theory is applied to switched systems and piecewise linear systems and to the general time-varying case. These optimal realizations are applied to obtain an optimal implementation of a simple multimode filter that allows the tracking of a target with low-complexity, small-wordlength hardware.<<ETX>>","PeriodicalId":113534,"journal":{"name":"Proceedings of the 27th IEEE Conference on Decision and Control","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125088914","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 approach not only yields the qualitative solution of the game (winning zones), but also defines a set of optimal open-loop controls for each initial state (Pareto-optimal security strategies, POSS). In this application the two components of the vector criterion essentially consist of the predicted miss distances resulting from missile firings of one aircraft against the other. They are evaluated by missile/target simulations with fixed strategies for both vehicles. Each of the POSSs associated with a particular initial state yields a maximum of missile effectiveness while maintaining a prescribed safety margin. The actual choice of one of the POSSs for guidance depends on the risk a pilot is willing to take. Computationally a POSS is approximated by the solution of an optimal control problem. Results with an F4 aircraft model and a generic missile model are presented. A comparison with a related concept, the combat game, is outlined.<<ETX>>","PeriodicalId":113534,"journal":{"name":"Proceedings of the 27th IEEE Conference on Decision and Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129451451","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 system to be controlled is linear, except for randomly jumping parameters which obey a discrete-time finite-state Markov process. A quadratic expected cost is minimized, for systems subject to additive Gaussian input and measurement noise. It is assumed that the system structure (i.e. jumping parameters) is known at each time. A separation property enables the authors to design the optimal JLQ controller and optimal x-state estimator separately. Based on the appropriate controllability and observability properties for discrete-time jump linear systems, the infinite-time-horizon JLQG problem is solved. The optimal infinite-time-horizon JLQG compensator has a steady-state control law but does not have a steady-state filter. A suboptimal JLQG compensator, using a filter which converges to a steady-state filter, is then constructed.<<ETX>>","PeriodicalId":113534,"journal":{"name":"Proceedings of the 27th IEEE Conference on Decision and Control","volume":"119 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126894196","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}

They show that their earlier proofs for convergence to bounded regions and for the existence of a finite number of equilibria are independent of the symmetry of the interconnection matrix and thus are also applicable to more general nongradient dynamic neural nets. However, when the interconnect matrix is asymmetric, the network is not guaranteed to have only (finite) equilibria as its limit set. The authors present computer simulations of a three-neuron network which demonstrate the coexistence of two stable equilibria within the same quadrant. The three-neuron example hence contradicts a recent theorem in the literature.<<ETX>>","PeriodicalId":113534,"journal":{"name":"Proceedings of the 27th IEEE Conference on Decision and Control","volume":"69 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129079185","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}
