摘　　要：综合考虑飞机机体、机轮、轮胎和跑道状况的特性,建立了飞机防滑刹车的滑跑模型。对于刹车系统的非线性和不确定性,难以精确控制的特点,采用模糊控制来解决刹车控制问题。在MATLAB模糊逻辑工具箱中对控制器进行设计,并将模糊控制器与滑跑模型应用于SIMULINK仿真环境,建立整体仿真模型。仿真特性曲线表明:建立的整体模型和应用模糊控制比较合理,飞机的刹车性能良好。Taxiing model of aircraft antiskid brake system was established by compositive considering aircraft economy, aircraft wheel, tyre and runway status. It＇s difficult to precise control for non-linear and uncertainty of aircraft, so braking control problem was solved by adopting fuzzy control. Controller was designed in MATLAB fuzzy logic toolbox, and fuzzy controller and taxiing model were used in SIMULINK condition, and the whole simulation model was set up. Characteristic curves of simulation show that whole simulation model and using fuzzy control are comparative with reason; brake performance of aircraft is all right.
