摘要
为了验证主轮差动刹车系统在飞翼布局无人机上应用的可行性,以某飞翼无人机为对象,在综合考虑了无人机的机体、起落架、轮胎等特性的基础上,建立了飞翼无人机地面滑跑仿真模型。它由无人机机体动力学模型、轮胎跑道间摩擦系数模型、轮胎跑道间结合力矩模型、机轮动力学模型、电液伺服阀模型以及刹车装置模型等组成。提出主轮刹车系统进行航迹纠偏控制的方案,并进行了仿真验证。仿真结果显示应用主轮差动刹车系统进行航迹纠偏控制是可行的。
In order to validate the feasibility of the application of main wheel differential brake to flying wing UAV. With background of a certain flying wing UAV, on the basis of characteristics of the UAV body, tires and landing gears, established the simulation model of flying wing UAV during ground roll. It is made up of UAV body dynamic model,coefficient of friction model between tire and runway, combination moment model between tire and runway, aircraft wheel dynamic model, electro - hydraulic servo valve model, braking instrument modal and so on. Put forward the scheme of main wheel differential brake system to trajectory bias rectification control and validate the scheme through simulation. The results of simulation show that main wheel differential brake system can realize the trajectory bias rectification control.
