Abstract:

This paper studies the experimental application of a fuz zy controller t o turbojet engines. Firstly, a method of experiment and the mathematical model s of some parts are proposed. Secondly, the idea of on-off design for the con troller and a model of the controller are put forward. Finally, the speed digital cont rol system for the turbojet engine is tested. The results show that the fuzzy c ontroller has simple design and good characteristics of controlling performance. Meantim e, the fuzzy controller has an ideal effect of compensating for the influence o f non-linear function on the system.
