针对弹道高度较低且终端状态受多种约束的固体火箭,对传统能量管理方法进行了改进。改进方法增加了基于标准飞行程序的预测步,根据弹道高度较低的特点在计算总视速度模量环节扣除了气动阻力引起的视速度损失,基于终端状态所受的多种约束提出计算需要视速度模量的新方法。仿真结果表明改进方法可以提高能量管理效率、减小速度偏差,验证了在低弹道飞行试验中的实用价值。

In view of the solid rocket with multi-constraints and lower trajectory, improvement was implemented for traditional energy management. The improvement includes addition of an integral process based on the standard flight program. Besides, the improvement deducts expense of apparent velocity resulting from pneumatic power according to the character of lower trajectory, and the new method of calculating gross apparent velocity module has been introduced based on multi-constraints. Simulation results show that improved method can not only boost energy management efficiency, but also reduce velocity error, and validate practical value used in lower trajectory flight test.
