高超声速飞行器编队协同飞行轨迹规划方法

Formation Cooperative Trajectory Planning for Multi-Hypersonic Vehicles

针对多高超声速飞行器编队协同飞行问题,提出基于多飞行阶段建模和自适应伪谱法的轨迹规划方法。首先,建立了高超声速飞行器运动模型。然后,面向编队协同飞行问题,建立了任务终端约束和构形约束,并基于编队形成段、稀疏编队段、紧凑编队段的多阶段划分对轨迹规划问题进行建模,在此基础上给出编队飞行综合性能指标函数。随后,提出基于hp自适应Radau伪谱法和序列二次规划的编队协同飞行轨迹规划方法。最后,通过仿真实验验证了多飞行阶段协同飞行轨迹规划方法的有效性。

A trajectory planning method has been proposed for the formation cooperative flying of multi-hypersonic vehicles based on the multi-stage modeling and adaptive pseudo-spectral method.Firstly,the dynamic model of a hypersonic vehicle is introduced.Then,the terminal constraint and formation keeping constraint are presented for the formation cooperative flying problem,and the trajectory is divided into three stages:formation form,loose formation and tight formation.On this basis,a comprehensive performance index is presented.Furthermore,the formation cooperative trajectory planning method is proposed based on the hp adaptive Radau pseudo-spectral method and sequential quadratic programming.Finally,the validation of the proposed method is verified by a group of simulation experiments.
