高速飞行器编队队形快速成形设计方法

Design Method of Rapid Forming for High-Speed Aircraft Formation

针对高速飞行器编队队形设计问题,提出了一种基于伪谱法和自适应策略的快速成形实现方法。首先,建立高速飞行器三维运动模型,为解决初始构型与期望队形偏差过大难以满足控制约束的问题,提出了一种考虑最低能量和最小偏转角度的队形设计原则,可自适应调整编队成形空间位置;然后,将高速飞行器编队控制问题转化为轨迹设计优化问题,并利用伪谱法实现各飞行器满足过程约束飞行轨迹的求解与优化;最后,对不同初始状态、不同偏差分布情况下的高速飞行器编队成形过程进行了数值仿真分析,验证了快速成形设计方法的有效性和鲁棒性。

Regarding the problem of the high-speed aircraft formation,the rapid forming implementation technique based on pseudo-spectral method and adaptive strategy is proposed.Firstly,the three-dimensional motion model of high-speed aircraft is established.In order to solve the control problem due to the large deviation between the initial configuration and the expected formation,the formation design principles by involving consideration of the lowest energy and the minimum deflection angle are deduced,and the formation forming location is self-adjusting.Then,the formation control problem is converted to the track design optimization,and the solution and optimization are solved by pseudo-spectral method.Finally,the simulation result verifies the effectiveness and robustness of the design method for rapid forming,which is based on the different initial states and the deviation distribution.
