A necessary and sufficient condition for complete controllability of the stage-by-stage changing linear non-stationary systems with varying dimension of the control vector is obtained; when the condition is satisfied the system can be transferred from any given initial state specified at the first stage to any final state specified for the last stage with the corresponding control actions. The condition of complete controllability for a stage-by-stage changing linear stationary system is expressed directly through the initial parameters of the system and is comparable with the well-known Kalman condition for the ordinary systems. The qualitative properties of controllability of such systems are revealed.","PeriodicalId":166223,"journal":{"name":"2020 15th International Conference on Stability and Oscillations of Nonlinear Control Systems (Pyatnitskiy's Conference) (STAB)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123527505","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}

Such solids have no global stress-free shape in Euclidean physical space due to the distributed defects, \"recorded\" into the solid during growing process. Nonetheless, in the framework of geometric approach in continuum mechanics the desired stress-free reference shape can be found in non-Euclidean space with specific (material) connection. For oriented solids, whose particles have to be identified with positions and orientations, such space can be represented by a submanifold in total space of principal bundle, defined over basic (conventional) material manifold. In such a case the deformation of growing solid can be generalized as smooth embedding from such space to total space of physical principal bundle. Invariants of connection on material principal bundle characterize the incompatibility of local deformations and can serve as cost functions in optimization problems.","PeriodicalId":166223,"journal":{"name":"2020 15th International Conference on Stability and Oscillations of Nonlinear Control Systems (Pyatnitskiy's Conference) (STAB)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131541860","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}

So for several decades one model or a family of forecasting models can work successfully, but when the amplitude ratio changes, they become inapplicable and other models should be taken that are more consistent to the new movement. The result is used to refine the model of the Earth’s rotation and to select a strategy for predicting the pole position, whose oscillation due to the atmosphere and the ocean circulation is non-linear.","PeriodicalId":166223,"journal":{"name":"2020 15th International Conference on Stability and Oscillations of Nonlinear Control Systems (Pyatnitskiy's Conference) (STAB)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130878476","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}
