A two-variable fuzzy-PI control algorithm based on the fuzzy reasoning

and a two-variable self-stunning fuzzy control algorithm based on the fuzzy reasoning with four inputs are provided.Then a new two-variable fuzzy-PI controller and the two-variable selfstunning fuzzy controller with four inputs are developed.The attention is focused on the research of those algorithms and the properties of those controllers

as well as their application to aeroengine control by computer simulation.As a result

a new method of aeroengine control is provided.
