摘要
针对无人机在起飞滑跑过程中,受到地面支反力和摩擦力的影响,其运动特性与空中飞行不同的情况,通过详细分析无人机在起飞滑跑过程中的受力情况,建立了无人机的地面滑跑纵向模型,并设计自动起飞纵向控制律,实现无人机地面滑跑、起飞控制;并在Matlab/Simulink平台上进行仿真,仿真结果表明所建立的模型可用,控制律效果良好,满足设计要求。
The longitudinal model of UAV in ground run was built based on the detailed force analysis while the friction force was taken into account, and the longitudinal control law of auto take--off was designed as the model had been built, then simulation results about auto take--off was given. The results show that the model built is accurate and the designed control law has a good effect.
