This paper presents a preliminary analysis of aeroengine control technology for CFM56-5B, CFM56-7B, V2500 in service and Next Generation LEAPX and GTF, which maily mounted on 150-seat aircraft. In this paper, it focuses on the analysis of FADEC system construction, fuel system,various control technologies, and overspeed protection. It also performs a contrastive analysis between the in service commercial aeroengine control echnology and next genereation aeroengine, both for 150-seat aircraft. After a preliminary analysis of differences among various techonologies, there is a conclusion and some suggestions in respect to new control techonologies.
