Uzunov O. The development of the theory of cyclic-modular modeling and design of mechatronic systems and devices

The work is devoted to improve of methods and algorithms for forming of mathematical models and of mechatronic systems with devices of hydroautomatics. The problems in the case of using of the known approaches are defined and defined the way of their solving. Investigated and identified patterns of the relationship of the process of operation, construction and properties of systems. Formulated new theory of cyclic-modular modeling and design, and principles of forming of systems and their models, which provide the structural adequacy of the creation phase. A new concept of modeling, which uses a representation of an object as a superposition of two parts - an invariant, which displays the process of operation, and growing, which reflects the accumulation of properties. A set of techniques that are implemented in software is developed. In practical examples show that the use of the approach allows due to reducing of number of tests and of iteration cycles reduce the time of solving of tasks on (20-35%) and by improving the quality of models extend the functionality of systems.
