摘　　要：为使航空发动机在较广的运行条件下满足控制需求,采用四种不同的方法设计自适应模糊滑模控制器,用模糊控制逼近滑模切换控制项,并通过参数自适应律的设计,根据工况条件自动调整输出模糊集合中心。仿真比较了四种设计方法在航空发动机线性模型稳态点的控制效果和转速跟踪性能。结果表明,间接自适应模糊滑模控制和采用三条模糊规则的自适应模糊滑模控制方法的系统响应快、超调量小、转速跟踪能力强,综合控制性能较好。Aimed at meeting the control requirements of aero-engine under wide operation conditions,four different adaptive fuzzy sliding mode control methods were studied in this paper. Fuzzy control was applied to design the switching mode logic,and adaptation laws were used to adjust the center of fuzzy set as working environment changed. The control effect was tested at linear steady-state points of the aero-engine model and the tracking performance was compared in simulation. The analysis indicates that the indirect AFSMC and the AFSMC using three fuzzy rules obtain a faster system response and smaller overshoot,stronger tracking ability. Therefore these AFSMC methods achieve better integrated controlling performance.
