## A.V. Gulay, V.M. Zaitsev Intelligent models of energy-converting systems: construction and application

### Abstract.

An intelligent model of the energy-converting system is proposed, which is implemented by means of provision of the energy conversion scheme in the form of an net graph along with subsequent building of behavioral rules of crisp and fuzzy logic. Links of the PART-OF type are established between the considered system and graph nodes, what pertinently turns the net graph to a semantically oriented model of energy-converting system functioning. This simulation method ensures formation of a certain quantity of structurally oriented frames for allocated system functional blocks, where each of them conforms to an individual top of the net graph. Distinctive features of control procedures and diagnostics of the considered energy-converting system are achieved due to the identification of frames and slot, included to them. A bypass circuit is also presented for tops of the built net graph, as well as a sequence of actions for system dynamical control at different simulation levels. In order to provide possible account of experimental and expert main production rules of crisp and fuzzy logic have been worked out, which reflect combination and variation of a group of parameters, as well as facts of system features degradation in the course of time.
