Voronenko S. Automation of control processes of ship complex electric turbocharger power plant

The dissertation is dedicated to solving the problem of increasing the efficiency of operational control processes of ship electric power systems with turbocharger units. The object of research is systems of operational control of ship complex power turbochargers. The purpose of the research is to increase the efficiency of operational control of ship electric power systems with turbochargers. Researching methods include: power balance method – to construct a mathematical model of ship complex power turbochargers; methods of systems analysis from the standpoint of ‘state variables’ – to study the properties of the control system being created; principles of optimal control – to determine the control strategy of the pressure-charging system; fuzzy logic methods – for the adaptive controller synthesis; methods of the electric circuit theory – to analyze induction machines operation processes. For the first time, the task of control of ship complex power turbocharger units has been formalized on the basis of the criterion of energy efficiency of its operation, which takes into account the power balance in the system and provides the necessary pressure-charging degree of the main engine. For the first time, there has been suggested a new method of operational control of ship electric complex power turbochargers with the use of a fuzzy adaptive regulator of a pressure-charging system, which allows reducing fuel consumption in operational modes. The results of the research may be applied for automation of power systems and complexes, as well as in the educational process in educational and research institutions.
