Some of the critical and practical issues regarding the problem of health monitoring of multi-component human-engineered systems have been discussed, and a syntactic method has been proposed. The method involves abstraction of a qualitative description from a general dynamical system structure, using state space embedding of the output data-stream and discretization of the resultant pseudo state and...
We analyze the hierarchies of levels in multiscale systems and related description parameters and models. Then as the illustrations we propose some new formulations of problems and solution interpretations. At first we discuss the different types of chaos and turbulence in the hierarchy of levels. Secondly we consider cellular automata models with internal structures of the cells and multivalued solutions...
Wind turbine generator system (WTG) is a complex nonlinear system involving some uncertain disturbances, and its working states change multifarious. A fact was discovered that it showed the typical feature of hybrid system by analyzing its characteristics. Therefore, the hybrid dynamic model of WTG was built based on theory of hybrid automata, at same time hybrid control system was designed for solving...
