A kind of Strategy Based on Adaptive Fuzzy Control and its Application to Aero Engine Turbine Power

Aero engine turbine power is a typical nonlinear system with characters of time-variable, strong interruption, uncertainty and model complication. It is difficult to achieve good effects by traditional control methods. Adaptive stable control of aero engine power generation system is realized by using adaptive fuzzy control strategy based on variable domain. In this paper, the basic structure of adaptive fuzzy controller based on variable domain is elaborated at firstly, and then the adaptive fuzzy controller is designed by utilizing the adjustability of the contraction-expansion factor a on line and the adaptive law of factor alpha, finally, by the field tests and trial production, it is proved that the control scheme is reliable and effective.
