Research Of Aeroengine Control Based On Fuzzy Neural Networks

On the basis of analysis of the fuzzy control theory, aiming at such kind of multivariable aeroengine control system which is nonlinear and hard to model, after studying the application of fuzzy control theory in the field of aeroengine control, a new method of the variable damp fuzzy feedback for aeroengine control is proposed, which can determine the fuzzy control rules by establishing the fuzzy model of control object when the precise mathematic model is hard to establish. Some simulations are implemented to analyze the method and the result shows that the method can improve steady accuracy and the dynamic state quality of the system.Besides this, the combination about fuzzy control and neural networks theories with aeroengine control system is studied too. On the basis of introduction of the principle, design method, structure and function of the new structure, the result of simulation is provided. The simulating results illustrated that the method is feasible and available, and this kind of controller is quite approving. From all above, it is clear that the intelligent control technology has a nice prospect in the field of aeroengine control.
