In the fuel control system of a turbojet engine, the control algorithm directly influences the engine control performance. In this paper, the fuzzy control is used as the control algorithm. The principle of fuzzy control is explained. Two design methods are introduced. The first is the membership degree method on the basis of fuzzy sets theory. The second is the phase-plane method on the basis of engineering control. Microcomputers have rapidly developed and are applied in the engineering area. Here, a microcomputer is used to implement the function of the fuzzy controller, based on the phase-plane method. In the final section, we carried out the dynamic semiphysical simulation test for the fuel control system of a turbojet engine in small perturbation. And finally, some useful conclusions have been made.
