激光推进用于飞行器姿轨控制的分析与仿真

激光推进成本低、可靠性高,可用作飞行器的空间推进和姿态调整。建立了考虑反馈控制和激光推进的飞行器动力学模型,模型中的操纵控制项模拟了飞行器操纵系统和激光推进产生的力、力矩。详细研究了确定操纵项的方法,使用自适应飞行控制律,给出一种通过求解线性方程组确定操纵控制项的方法。以圆形盘旋轨迹为例,进行了数值模拟,计算结果显示,激光推进下的飞行器能很好按照目标轨迹飞行,并对计算结果进行了分析。

Analysis and Simulation of Vehicle Attitude and Orbit Control by Laser Propulsion

Laser propulsion can be used in space propulsion and attitude control for its low cost and high reliability.A dynamical model of the air vehicle which takes the feedback control and laser propulsion into account is proposed,and the control terms in the model equations simulate the forces and moments produced by the control system and laser propulsion.Methods for determining the control terms are studied,adaptive flight control law is used and a specific way through solving linear equations is put forward.The proposed method is tested by applying it to the hovering alongside a circle.Numerical results show that the vehicle flies along the prescribed orbit,and results are also briefly discussed.
