摘要
在分析滑移率控制式飞机防滑刹车系统的工作原理基础上,提出了一种基于最佳滑移率式的飞机防滑刹车系统的模糊控制方法。以某型飞机为例,将该方法在MATLAB环境下进行了数字仿真。结果说明:模糊控制方法能够达到较好的刹车控制效果,并具有较强的鲁棒性;采用基于滑移率式的模糊控制算法可以大大地提高飞机防滑刹车效率,特别是在跑道积雪情况下的刹车性能提高显著。
By analyzing the principle of aircraft anti-skid braking system, an optimal control method of aircraft anti-skid braking system based on wheel slip-ratio is presented, and the fuzzy control is used to realize the optimization of aircraft anti-skid braking system control performance. The computer simulation is made for an aircraft anti-skid braking system, and the results show that the fuzzy control method can achieve an ideal control effect and has a strong robust characteristics, and the braking efficiency has been improved greatly by controlling wheel slid ratio,as compared with controlling sliding velocity on the worse runway.
