本文研究的内容是,如何用微分动态编程(DDP)方法来计算垂直发射导弹的最优推力矢量控制.研究结果证明了DDP方法控制收敛来克服收敛困难的技术可行性.考虑的问题是要求导弹作大攻角机动飞行.同控制偏转的极限一样,这个问题意味着是非线性系统动力学.计算出来的最优弹道代表了可以获得导弹某些给定的物理特性的性能.因此有可能用DDP计算出不同导弹约束条件的相对重要程度.
The content of this paper is how to calculate the optimal thrust vector control of vertical launched missiles by using the differential dynamic programming (DDP) method.The research results show that the DDP method can control the convergence to overcome the technical feasibility of the convergence difficulties.The problem to be considered is that the required missile As with the limits of control deflection, this problem implies a nonlinear system dynamics. The calculated optimal trajectory represents the performance that can be obtained for some given physical property of the missile, so it is possible to use DDP Calculate the relative importance of different missile constraints.
