分析了远程滑翔导弹地理约束的形成,建立了三自由度弹道模型、气动模型与气动热模型.在考虑地理等实际约束下,建立了多阶段多约束弹道优化模型.利用直接打靶法将此最优控制模型转化为非线性规划问题,并采用序列二次规划算法进行解算.结果表明,研究方法适合于解决考虑地理等约束的远程滑翔导弹弹道问题,所得的最优弹道更有利于满足实际作战需求. The formation of the long-range gliding missile’s geographical constraint was analyzed and the three-degree-of-freedom trajectory model, the aerodynamic model and the aerodynamic model were established. The multi-stage multi-constraint trajectory optimization model was established considering the actual constraints such as geography. The optimal control model is transformed into a nonlinear programming problem and the sequence quadratic programming algorithm is used to solve the problem.The results show that the method is suitable for solving the problem of the trajectory of a long-range gliding missile considering the constraints of geography and other constraints, and the optimal trajectory obtained is more favorable for satisfying the actual Battle needs.
