无人驾驶飞机单侧弹射投弹时会产生干扰力矩,影响无人机稳定飞行。针对这个问题,对投弹后无人机恢复导弹发射前姿态的过程进行了分析,描述了投弹对无人机的干扰问题。以小扰动状态方程为基础,将干扰力矩作为输入,并在控制律优化设计后将自动驾驶仪控制律作为控制方程代入小扰动模型。在挂载导弹到机身距离较小的情况下,对投弹后无人机姿态角的变化进行了建模、仿真和结果分析。仿真结果表明,在单侧投放导弹后,无人机能够很好地稳定飞行姿态,控制无人机平台以投弹前航向继续稳定飞行,为第二枚导弹的顺利投放做准备。 Unmanned aerial vehicles will cause unmanned aerial missile bombs, affecting the stability of UAV flight. In response to this problem, the process of recovering the posture of the missile before the launch of the UAV after the bombing is analyzed and the interference of the bomb on the UAV is described. Based on the small perturbation equation, the disturbance torque is taken as input. After the optimal design of control law, the autopilot control law is used as the governing equation and is substituted into the small perturbation model. The change of the attitude angle of UAV after the bombing was modeled, simulated and the result analyzed under the condition that the distance between the missile and the fuselage was relatively small. The simulation results show that UAS can stabilize flight attitude after unilateral missile deployment, and control the UAV platform to continue its stable flight in the projectile flight direction in preparation for the smooth launch of the second missile.
