摘要:
飞机防滑刹车控制系统中对滑移率的研究是近年研究的热门课题。根据飞机地面滑跑的受力分析建立了飞机的非线性动力学数学模型,提出了一种基于最佳滑移率方式的飞机刹车系统模糊控制律;在刹车过程中,提高刹车效率的重要前提是对飞机速度的准确估计,因此提出了基于扩展卡尔曼滤波算法的飞机速度精确估计的方法,将估计飞机速度的最优值作为防滑控制律的输入,实现系统状态的估计。对所提出的算法进行仿真验证,结果表明:基于扩展卡尔曼估计的模糊控制可以准确估计出飞机滑跑时的速度,实现滑移率的最优控制,改善飞机低速段滑移率控制,提高飞机刹车性能和效率。

Abstract:
The slip ratio of the aircraft anti-skid braking control is a popular research topic in recent years. We, establish the aircraft nonlinear dynamic mathematical model according to the force analysis of the motion on the ground and put forward the fuzzy control of optimal slip ratio. We propose an aircraft velocity accurate estimation method,using extended Kalman filter for brake efficiency improvement. The input of fuzzy control is optimal value estimated by EKF and implemented the estimation of system state. The simulation software is used to simulate and validate the proposed algorithm; the results and their analysis show preliminarily that fuzzy control with EKF estimation algorithm can estimate the aircraft velocity and realize aircraft ABS optimal slip ratio control. The slip ratio is ameliorated in lower velocity; brake performance and efficiency is improved.
