Kharchenko R. Hybrid intelligent networks for ship microclimate systems.

The thesis is devoted to the solution of an important scientific and applied problem - to increase the operational efficiency of ship systems of a comfortable microclimate. The theoretical and practical foundations of increasing the efficiency of operation, management and ensuring trouble-free operation of microclimate systems based on intelligent technologies are considered, which ensures a reduction of operating costs and improvement of microclimate parameters in the ship's premises in compliance with social safety requirements. The paper analyzes the directions of solving the problem of providing spaces for vessels with comfortable microclimate conditions together with improvement of technical and economic indicators. It was proved that the introduction of modern intelligent systems for the operation of climate equipment and the development of methods for monitoring and diagnosing its operation are promising. The directions of research devoted to the problem of improving software and the introduction of microclimate systems of modern intelligent hybrid networks are substantiated. In the main part of the thesis theoretical foundations of the operation of the ship's climate systems are considered, mathematical models and algorithms are obtained that take into account the dynamics when changing the parameters of the air mixture and other influences. Features of operation are described by mathematical models with various methods of management and degree of the account of influences which in turn have a different level of quality and adequacy of result. A software implementation of the system was carried out taking into account disturbing factors and using parallel operation of several regulators. The algorithm of work and the module of the dynamically connected library are developed, the necessary analytical expressions are presented. Based on the compiled algorithms, a program module has been developed that allows calculating the parameters and performing simulation simulations. For the simulation, the expert operational data of real ships, obtained in real operating conditions, were used. In the final section of the paper, an alternative method of operating microclimate systems with the use of intelligent systems in a single complex is considered. Analytical expressions for constructing a hybrid intelligent network are obtained. With the help of the proposed method, the system parameters are calculated using the example of individual nodes whose values coincide with the standardized ones for the satisfactory operation of these systems. The influence of perturbing factors, obtained formula expressions for the calculation of characteristics, is considered. The knowledge bases for the synthesis of the corresponding regulators are presented in a tabular form. In addition to the tabular dependences, graphical curves are shown reflecting the dependence of parameters on the model, obtained using a computer program. The developed system is suitable for operation in automatic or supervisory mode and allows to form tasks to local nodes, putting the operation of microclimate systems to a new level of comfort.. System for diagnosing the technical condition of equipment is developed, which differs in the function of accounting for expert experience.
