摘要
根据无人机在三轮着地滑行时的运动特性,建立了这一阶段的全量非线性模型,并在MATLAB/SIMULINK仿真环境下设计了该模型的仿真系统,加入了防滑刹车控制系统模型,使仿真更接近实际情况。提出了飞翼无人机基于阻力方向舵的滑跑控制方案,针对某飞翼无人机的着陆滑跑控制仿真结果表明,所设计的仿真模型可用;主轮刹车与阻力方向舵协调操纵进行滑跑控制的方法响应平滑,性能良好。
Based on the dynamical character＆tics for UA V with all wheels in ground motion, the whole nonlinear model was established. And the simulation system for the model was designed with the simulation environment of MATLAB/ SIMULINK. Because of including the anti-skid braking system model, it accurately reflects the actual characteristics of the UAV much more. The control system for a flying-wing UAV in ground motion was designed applying drag rudder. And the simulation results of the flying-wing UAV in ground motion during landing indicate that the model can be used, and the UAV control system applying rear wheel braking and drag rudder control corresponded has smooth control response and good performance in ground motion.
