提出了一种基于规则的模糊逻辑飞行控制系统的设计方法,用以解决某教练机训练系统中数学模型时变性和不确定性问题。为了避免建模的困难,某教练机飞控系统采用模糊逻辑控制设计其控制律,结合飞行员的操纵经验,对系统进行动态调整。以俯仰角为研究对象,利用MATLAB中的fuzzy工具箱实现了模糊控制器设计,给出了俯仰角模糊控制器的控制曲面视图,并在SIMULINK仿真环境下建立了仿真模型。结果表明,所设计的模糊逻辑控制器满足操作品质的要求,具有较好的鲁棒性,对教练机驾驶训练仿真平台的飞行控制系统设计具有一定的应用价值。

In order to solve the problem of mathematic model＇s instability and uncertainty in training system of a certain training plane, this paper presents a method of flight control system of fuzzy logic based on laws. This flight control system for a certain training plane adopts fuzzy logic to design controlling laws, and combines with pilot experiences to adjust system dynamically for avoiding modeling. The introduction is based on pitch angle. Fuzzy controller is designed by utilizing the fuzzy logic toolbox of MATLAB, and the control surface view is figured. Moreover, the simulation modal is also built up in SIMULINK. The result indicates that the fuzzy longic controUer satisfies the quality requirement of flight control and has application values.
