The application of an expert system for simulation investigations in the aided design of ship power systems automation

摘要

A structure and function of information system for aided design of ship power subsystem automation is presented. More detailed a function of evaluation of design solutions based on simulation investigations is described.Data describing a designed power subsystem is introduced in interactive mode to an expert system, then production rules evaluate correctness to the substance and form of the design. In the case when there are no mistakes, the expert system creates simulation model of designed subsystem and calls program matlab-simulink. After a simulation session the program environment returns to the expert system.In the paper a knowledge representation of designed ship power subsystem, and a choice of component model structures of subsystems, which enable an application of production rules for simulation models creation and design correctness evaluation are shown. Also an algorithm of simulation models creation of designed subsystems and an exemplary session of simulation investigations of ship propeller subsystem are presented.
