Design of a fuzzy logic controller for a jet engine fuel system

Abstract The design, implementation and evaluation of two types of fuzzy logic controllers (FLC) are presented. The system under consideration is the control of fuel delivery in a jet engine test bench. Two methods of designing FLCs were experimented with. The first method included the development of a tool that inputs the rules, membership functions, and outputs the appropriate consequences. The second method was based on bivariante curve development and scaling. The evaluations of the proposed controllers were performed with an existing proportional–integral (PI) controller. Both of the design methodologies were proven to be superior in comparison with the conventional controller currently utilized for the control of combustion pressure on jet engines.
