Modelling of the ship diesel engine as an object of control on the basis of fuzzy logic

The work problem is creation of adequate model of a ship diesel engine on the basis of expert systems which should consider technical and technological parameters of the certain engine. The modular structure of model should allow changing algorithms of management of object that will allow estimating their efficiency and perceptivity of their further development. As object of control the diesel engine 6ЧН 15/18 (3Д6Н) has been chosen. For improvement of quality of the transient processes occurring in the engine, it has been decided to use fuzzy-neural network at creation of its model. In the course of carrying out of experiments at the loading stand the data files characterizing behavior of the control system and responses of the control object have been registered. Also the data file characterizing change in capacity, produced by the engine in the course of work has been collected. Modelling was spent with use of package MATLAB Simulink. The received system after test has confirmed the adequacy to real diesel engine and possibility of its using for working out and testing on its basis of control systems.
