提出了一种新的航迹优化算法,它通过对巡航弹动力学模型离散化,将TF/TA航迹优化直接转换为非线性规化问题,航迹约束转化为非线性规划的代数不等式约束,求解非线性规化问题产生全局最优的飞行航迹。并且提出了简单实用的性能指标,使最优航迹不仅能紧密跟踪地形,而且能自动回避危险和障碍。计算结果表明,该算法能产生平滑的TF/TA三维航迹,且能直接生成飞行航迹控制器的控制命令。
A new trajectory optimization algorithm is proposed, which converts the trajectory optimization of TF / TA directly into a nonlinear regularization problem by discretizing the dynamics model of cruise missile. The trajectory constraints are transformed into algebraic inequality constraints of nonlinear programming , Solving the nonlinear regularization problem produces the global optimum flight path. And put forward a simple and practical performance index, so that the best track can not only closely track the terrain, but also automatically avoid the dangers and obstacles. The calculation results show that the algorithm can generate a smooth TF / TA three-dimensional trajectory, and can directly generate the flight path controller control commands.
