Its implementation includes two stages. At the first stage the transition to fuzzy description is performed. A nonlinear system is replaced by the equivalent Takagi-Sugeno fuzzy model. This allows describing the behavior of the initial system in the given area of the phase space via a set of linear models weighted by membership functions. At the second stage the reachability sets of the system are estimated on the basis of generalization of the method of invariant ellipsoids. The numerical testing results that allow assessing the conservatism of the obtained estimations are presented.","PeriodicalId":395462,"journal":{"name":"2018 14th International Conference \"Stability and Oscillations of Nonlinear Control Systems\" (Pyatnitskiy's Conference) (STAB)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127025511","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 state of the system is unknown, but there is an equation of measurement in discrete times. The initial state and disturbances are restricted by joint integral constraints. According to measurements, the information set is introduced that contains the true state of the system. The preliminary aim of control consists in minimization of the terminal criterion depending of the information set. We suggest some statements of the problem based on the separation of control and observation processes. The optimal instants of transition from estimation to control are looked for as well. The approach is applied to systems with the deviation of time of retarded and neutral types, to parabolic and hyperbolic partial differential equations.","PeriodicalId":395462,"journal":{"name":"2018 14th International Conference \"Stability and Oscillations of Nonlinear Control Systems\" (Pyatnitskiy's Conference) (STAB)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122783941","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}
