Influence of the type of membership functions of fuzzy variables on transient processes in an electric drive

Abstract

The paper deals with the influence of the type of membership functions of fuzzy variables on transient processes in an electric drive. The membership functions of fuzzy variables of S-shaped type and triangular type are proposed for consideration. To identify the dependencies of the influence of these functions, the article offers simulation modeling in the Matlab software environment, the Simulink application. The system of frequency converter - asynchronous motor (FC-AM) was chosen as the considered control system. Transient processes in the considered system with various types of membership functions are shown. The results of the work are summarized in the conclusions.
