摘　　要：针对无人机在自动起飞过程中,地面滑跑阶段的运动特性与空中飞行时不同的情况,通过详细分析无人机的地面转弯受力情况,建立无人机的地面滑跑侧向模型。采用操纵前轮偏转,设计自动起飞侧向控制律,以方向舵为辅助来纠正无人机滑跑过程中出现的侧向偏离,实现无人机地面滑跑侧向控制。并在Matlab/Simulink平台上对其仿真,仿真结果表明所设计的模型可用,控制律效果良好,满足设计要求。According to the different situation between ground run and flight of UAV, the lateral model of UAV ground run is built based on the detailed force analysis while UAV is swerving. A scheme of nose wheel steering control is adopted to design the lateral control laws of UAV ground run. The lateral deviation in UAV ground run is corrected by the assistance of rudder. The lateral control of UAV ground run is realized. The simulation model of lateral control of UAV ground run in Matlab/Simulink is given. The simulation results show that the model built is accurate and the designed control law has a good effect.
