摘要
研究飞机在着陆过程中地面滑跑阶段的运动特性,为了准确建立无人机着陆动态模型,利用飞机全电刹车系统的组成及工作原理,建立了六自由度飞机全电刹车系统整体模型,采用滑移率式控制方式对飞机进行防滑控制。针对某型飞机的着陆滑跑过程,在MATLAB/SIMULINK仿真环境下进行了数字仿真,得出了飞机地面滑跑刹车的动态响应。结果表明,所建立的机体及刹车系统模型合理有效;采用参数自调节模糊-PID方法控制的全电刹车系统具有良好的作动响应及刹车性能。
Based on the dynamical characteristics of aircraft in ground motion during landing process, we set up a six - degree freedom aircraft electric braking system model by investigating the composition and principle of the elec- tric brake, and the slip ratio control method was applied for anti - skid control. For a certain type of aircraft in ground motion during landing, the simulation system was designed with the simulation environment of MATLAB/SIM- ULINK, and the aircraft ground dynamic response of braking was concluded. The results show that the aircraft model and braking system model established in this paper are basically correct and the electric braking system controlled by the fuzzy - PID control method has good actuating response and braking performance.
