By using the Lyapunov functionals, the allowable bounds for the structured and unstructured uncertainties as well as the intensities of the stochastic disturbances are established to maintain the mean-square asymptotic stability of the composite stochastic systems. For the unstructured uncertain systems, the robustness bounds are obtained directly from the system matrices even without solving the Lyapunov equation. A specific example is given to illustrate the results.","PeriodicalId":297258,"journal":{"name":"1992 American Control Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121991850","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 important application area for sampling prefilters in H<sub>∞</sub>, is the problem of designing optimal prefilters in the context of sampled-data H<sub>∞</sub>, optimal control. The problem is to estimate a given linear function of the state of a continuous-time plant at discrete time instants. In this problem the process noise is a continuous L<sub>2</sub>-signal, and the estimation error is a discrete signal in l<sub>2</sub>. A continuous-time sampling prefilter is then designed so as to achieve an H<sub>∞</sub>, performance bound. Conditions for the existence of a sampling prefilter that satisfies the performance bound are obtained, and explicit formulae for a filter which achieves the performance bound are given. It is also shown how the filters studied in this paper can be applied to the design of optimal prefilters in sampled-data H<sub>∞</sub>, optimal control.","PeriodicalId":297258,"journal":{"name":"1992 American Control Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124789912","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 control design model is based on the linearized aircraft model. The unmodeled high frequency dynamics are ignored in this model. Singular perturbation method is used to analyze the effects of the unmodeled high frequency dynamics of the proposed controller. It is shown that the unmodeled dynamics affect the poles of the closed-loop system in the order of O(¿) only.

Both the controller and the original plant are redesigned so as to yield the same original closed-loop properties with a minimal active control effort. The initial linear controller before plant redesign is not restricted; it could be static or dynamic. We call this the optimal mix problem since we optimally mix parameter changes of the plant with parameter changes of the controller. The problem requires matching the entire plant matrix of the original system (before and after redesign). The problem is reduced to a standard mathematical quadratic program. Hence globally optimal answer is obtained in a finite number of steps. The applicability of the optimal mix theory to a general mechanical system is demonstrated by numerical examples of a spring-mass-damper system.","PeriodicalId":297258,"journal":{"name":"1992 American Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129617755","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}
