摘　　要：针对方案制导超音速火箭靶弹平飞段供靶性能优化问题,提出了一种俯仰程序角优化方法。考虑靶弹弹道始末端点约束及平飞段性能约束,在火箭靶弹纵向飞行平面内建立起俯仰程序角优化设计模型。基于Gauss伪谱法将飞行过程约束转化成对俯仰程序角的约束,将最优控制问题转换为对俯仰程序角的非线性规划问题;利用序列二次规划算法求解。仿真结果表明,该方法能够快速获取最优俯仰程序角,并且具有良好的鲁棒性,为实际工程设计提供参考。An optimization method of pitch program angle is proposed for the optimization problems of level flight trajectory of supersonic rocket target. Considering the initiation and impact point of rocket target and the level flight state constraints, the pitch program angle optimization model is built on the longitudinal flight plane of rocket target. The Process constraints are transformed to the pitch program angle constraints, and the optimal control problems are translated to the nonlinear programming problems based on Gauss pseudo spectral method. And then the nonlinear programming problems are solved by sequential quadratic programming method. Simulation results show that this proposed method can quickly obtain the optimal program pitch angle, and has good robustness.
