拖曳系统中运载器航迹控制律研究

Research on the Towed-Vehicle Flight Path Control Law in a Towed System

拖曳系统的飞行性能是评价拖曳系统可行性的一项基本内容,而要求解拖曳系统的飞行性能,则必须解决拖曳系统中运载器的航迹控制问题。在飞行器“准平衡”的假设下,研究了拖曳系统在铅垂面和水平面内飞行时运载器的航迹控制律,并进行了仿真计算。计算结果表明,所采用的控制律可以实现运载器跟随拖曳飞机的飞行航迹。

The flight performance of a towed system is the basis for evaluating the system＇s feasibility. The precondition of getting the system＇s performance is to solve the issue of flight path control laws of the towed vehicle in the system. Under the hypothesis of the vehicle quasi-equilibrium, this paper studies the flight path control laws of the vehicle when the system flies in a vertical plane or a horizontal plane. The simulating results indicate that these flight path control laws can ensure the vehicle flies following the flight track of the towing plane.
