Topalov A. Specialized computer system of parametric control and controlled stabilization of floating structures

Dissertation’s research is devoted to topical issues of development of models and methods for synthesis of branched structures and components of specialized computer systems of parametric control and controlled stabilization of floating docks through the use of methods of technical diagnostics, intellectual control approaches and technology of the Internet of things. The aim is to improve the reliability of data processing and to increase the efficiency of control processes in real time. For the first time a functional model of a specialized computer system of parametric control and controlled stabilization of floating dock has been developed. It is characterized by the use in its components of technical diagnostics, intelligent control methods and technology of the Internet of Things, which allows to increase the reliability of data processing and quality indicators of the control processes and to increase the level of diversification of the devices for monitoring operating parameters. The method of technical diagnostics of sensory components of floating dock is improved based on the periodic testing of hydrostatic fluid level sensors with the help of the developed VHDL-model, which allows to increase the accuracy of measurements and to reduce the duration of preventive maintenance of information and measuring equipment. The method for optimization of the structure of fuzzy controller is developed based on the intellectual reduction of the rule base and the spatial mathematical model of floating dock is improved by taking into account the mutual influence of the dock’s and vessel’s hulls. It allows to increase the level of mathematical formalization in the synthesis of the computer components of draft control, as well as list and trim stabilization for their hardware implementation. For the first time, a model of operator interaction with a specialized computer system of parametric control and controlled stabilization of floating dock based on the use of web servers and development of web-oriented human-machine interfaces is offered, that allows to expand the possibilities for distance control of floating dock operating parameters.
