Abstract: Self-stuning technicalization was introduced into the fuzzy control algorithm based on the fuzzy-reasoning with four inputs.A new two-variable self-stuning fuzzy control algorithm was synthesized based on the fuzzy-reasoning with four inputs.Then a two-variables self-stuning fuzzy controller with four inputs has been designed.The research focuses on the algorithms and the property of this controller,as well as its application in aeroengine control by computer simulation.The results show that this method is feasible for the aeroengine control system.
