Such realizations have been linked to balanced realizations. The theory is extended to the synthesis of minimum-sensitivity generalized state-space models for singular linear systems. A scalar sensitivity measure is defined, and the minimization of the measure over all admissible realizations is considered. Since minimal realizations are not required to be related by a similarity transformation, the optimization problem is more complex. A criterion is given for determining optimal sensitivity structures. In the nonsingular case, the criterion reduces to the familiar result. The simple example of the right-shift operator is considered.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"23 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":"116349982","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 assumed that a medium-scale flexible manufacturing system consisting of three to eight machines with overlapping functionality but possibly different effectivity is to be run under the JIT (just-in-time) philosophy. This means that all jobs have to meet their due dates but the starting times of the processing (due dates for delivered parts or previous stages of the production) should be as late as possible. Dynamic online scheduling means that the scheduling algorithms must react to the distances in the production process within short periods of time, typically some seconds to a few minutes. Under this constrain, an exact optimization cannot be achieved because of the enormous complexity of the problem. A mathematical description of the system is presented, and possible approaches to the generation and improvement of suboptimal schedules based on priority rules, and the prediction of the behavior of the system under the regime of such rules, are discussed.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"1 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":"116392509","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 assumed that the system matrices are unknown but bounded. A nonlinear control law is derived so that the tracking error in the closed-loop system is uniformly bounded and tends to a certain small neighborhood of the origin. The error dynamics are asymptotically decoupled in an approximate sense. The controller includes a reference trajectory generator and uses the integral feedback of the tracking error. Using this result, a flight control system is designed for the control of roll angle, angle of attack, and sideslip in rapid, nonlinear aircraft maneuvers. Simulation results are presented to show that large, simultaneous lateral and longitudinal maneuvers can be performed in spite of the uncertainty in the stability derivatives.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"225 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":"122106630","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}

Particular emphasis has been placed on determining when chaotic motion might exist from a knowledge of the unstable limit cycles predicted by the Tsypkin method, the largest amplitude unstable limit cycle being approximately sinusoidal. It is shown that this sinusoidal limit cycle can be calculated quite accurately by the describing function method, and it is found essentially to bound the region of chaotic motion. The chaotic motion gives the appearance of jumps between two or more of the unstable limit cycles found within the region. These unstable limit cycles exhibit two or more oscillations per half period, or spirals if viewed on a phase plane, and their peak amplitudes can be predicted approximately from consideration of the relay switching levels and the DC gain of the linear transfer function.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"10 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":"116872102","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}

Two methods for checking the robust stability in a perturbation domain of interest are considered. The first is the classical positivity checking approach based on the Routh-Hurwitz theorem and minima search, and the second is the polytopic polynomial approach with a dynamic perturbation domain dividing technique. Both approaches can be employed to compute the real-structured singular value or the real multivariable stability margin and to locate all unstable regions in a given perturbation domain.<<ETX>>","PeriodicalId":156565,"journal":{"name":"Proceedings of the 28th IEEE Conference on Decision and Control,","volume":"33 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":"128301192","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}
