Firstly, a generalized Lyapunov-Krasovskii theorem is proven. Secondly, the technique of parameter-dependent full-rank right annihilator of matrices is used to deal with the uncertain reset time instants caused by output matrix uncertainties. Based on this, several necessary and sufficient conditions for dissipativeness of reset mappings are established. Finally, some delay-independent and a delay-dependent robust stability results are given in terms of linear matrix inequalities (LMIs) by using certain kind of Lyapunov-Krasovskii functionals. An illustrative example is also given to explain the proposed results.","PeriodicalId":233004,"journal":{"name":"World Congress on Intelligent Control and Automation","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122421961","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}

Based on Lyapunov stability theory, the adaptive controllers and corresponding parameter update rules are constructed to make the states of two diverse chaotic systems asymptotically synchronize up to the desired scaling matrix and to estimate the uncertain parameters.

Immune system is regarded a remarkable mechanism capable of self-organizing to best strengthen its function for defending outside attacks. As such, the Artificial Immune System (AIS) theory is gradually adopted in designing optimal computation systems. In the study, an extension AIS(EAIS) shows antibody affinity to deal with enormous spectrum data and also characterizes Gray Matter (GM), White Matter (WM) and Cerebral Spinal Fluid (CSF) to highly benefit doctors and patients.

The perturbation is formed by a polytopic which is spanned by a number of constant known matrixes. By using condition of completeness, Lyapunov asymptotic stability theory and linear matrix inequality (LMI) method, delay independent quadratic stability conditions and the switching law of the uncertain delayed switched system are derived. Then by defining linear transformation, the delayed system can be converted to a delay-free system, and consequently delay dependent quadratic stability conditions and the switching law of the uncertain delayed switched system are obtained. The simulation results show the validity of the switching law.","PeriodicalId":233004,"journal":{"name":"World Congress on Intelligent Control and Automation","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128854704","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}

This design method was also extended to the case where only delayed state is available for the controller. The example of balancing an inverted pendulum on a cart demonstrates the effectiveness and applicability of the proposed design methods.","PeriodicalId":233004,"journal":{"name":"World Congress on Intelligent Control and Automation","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132954089","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 order to expand the search space and decrease the cross-correlation among the sub-sources, we propose to perform nonlinear transformation for the cost function. The real coded genetic algorithm is also proposed to search the optimum solution, which can overcome the drawbacks of traditional gradient search technique being likely tend to fall into local minimums. This novel method can be applicable to instantaneous or convolutive mixture models with stationary or non-stationary input signals. Simulation results demonstrate the algorithm not only has fast convergence performance and high accuracy, but also can improve the output SNR greatly.","PeriodicalId":233004,"journal":{"name":"World Congress on Intelligent Control and Automation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129342375","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}
