VECTOR MATRIX FUZZY CONTROL OF THE ROTATIONAL SPEED OF A TURBOPROP ENGINE FREE TURBINE

The methods of fuzzy logic have found wide application in control problems. However, when using the fuzzy logic apparatus, it is necessary to choose models of fuzzy logic operations, which are selected from empirical considerations. This makes it difficult to construct algorithms for solving specific problems. The use of «classical» operations is justified only for solving simple problems and does not require a large number of rules. The use of vector models aimed at ease of implementation, high speed and expansion of the application area is suggested. The use of the matrix device replaces the projections of the vector of the linguistic variable (term-set) with fuzzy vectors. The basic operations on fuzzy vectors are given in the works of Marcenyuk MA, on the basis of which the design of a vector fuzzy speed controller for a turboprop engine is considered. New is the use of a singleton base for the activation of fuzzy vector fuzzyfikator, the application of the method of difference areas as a method of defuzzification.
