摘要
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.
Abstract
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 for-mation and tight formation. On this basis,a comprehensive performance index is presented. Furthermore,the for-mation 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 simu-lation experiments.
