摘　　要：针对采用传统控制律的飞机防滑刹车系统鲁棒性差、机轮易在低速段出现严重打滑甚至脱胎现象等缺点,提出了一种新型控制律——模糊复合控制律;并在matlab6．5／simulink环境下,对采用这两种控制律的飞机防滑刹车系统分别进行了仿真研究;将两种情况下的结合系数和滑移率仿真曲线在同一坐标系下给出,结合曲线对两种情况下的刹车系统性能进行了比较分析,结果表明:采用模糊复合控制律的刹车系统鲁棒性增强,刹车效率提高,明显克服了因采用传统控制律而引起的诸多缺点。As operated by traditional control law, to the alreraft anti--skid braking system occurs many flaws, such as, bad robust, wheel easily skidding in low velocity, and so on. Basing on these characteristics, artlele puts forwards a new control law--fuzzy compound control law, Simulation on aircraft braking system applying the two control laws are performed on matlab6, 5/simulink platform. The curve of friction and slippage ratio are given respectively, and plotted in the same coordinate. Result shows that the braking system applying the new control law has more robust and higher braking efficiency, moreover, evidently conquers the flaws mentioned before.
