摘　　要：研究了航空发动机的模糊滑模控制方法,使航空发动机在较广的运行条件下满足控制需求。采用一维间接模糊滑模控制、二维直接模糊滑模控制这两种方法设计模糊滑模控制器,并通过仿真对比,分析了两种设计方法在航空发动机线性模型和用LPV建模法建立的非线性模型上的控制效果。仿真结果表明,二维模糊滑模控制方法具有响应快,对外界干扰不敏感,系统鲁棒性强且非线性跟踪效果好的优点,其控制效果优于一维模糊滑模控制方法。Aimed at meeting the control requirements of aero-engine under wide operation conditions, two different fuzzy sliding mode control（FSMC）methods were studied for simulation. A one-dimensional FSMC was designed for switch gain adjustment, and a two-dimensional FSMC designed to approach the SMC term. The two methods were tested at linear steady-state points. Linear parameter varying control was used to create non-linear dynamic process for verification. The analysis illustrates that compared with one-dimensional FSMC, 2D-FSMC obtains a faster system response, stronger robustness against external disturbance and better non-linear tracking effect, so it has more favorable control performance in simulation.
