| 摘 要： | 激光能够照射到的区域受到限制,飞行器只能在这个范围飞行并尽可能获得较大的速度.考虑两种不同的加速方式:竖直平面内直接加速和螺旋加速,使用程序调参飞行控制技术确定操纵面偏转角度,控制飞行器轨迹,并且给出了相应的仿真结果.结果表明,操纵控制下的飞行器能够按照预定轨迹飞行;使用螺旋加速方式,可以延长激光加速的时间,但是这两种加速方式最后得到的速度差不多, 而螺旋加速的操纵复杂,因此竖直平面内直接加速有一定的优势.

| Abstract: | During laser propulsion,the region that the laser beam can reach is restricted,so the vehicle can't fly beyond the region.The vehicle should obtain as much energy as possible.Two accelerating modes are considered: accelerating directly and accelerating spirally.Gain-scheduling flight control law is used to determine the deflexion angles of the control surface and control the trajectory of the vehicle,and the trajectory simulation results are obtained.The results indicate that under the control system the ve... |
