摘要：

针对滑翔段到巡航段的过渡段控制问题，在考虑地球自转和冲压约束及巡航段初始状态约束条件下，建立了导弹控制律设计模型．运用Gauss 伪谱法将最优控制问题转换为非线性规划问题，利用SNOPT 对非线性规划问题进行求解．仿真结果表明Gauss 伪谱法对导弹滑翔段到巡航段的过渡段最优控制律求解是有效的。

Abstract:

Aiming at the control problem of glide stage to cruise stage，considering rotation of the Earth and stamping constraint and initial
state constraint of the cruise stage，control law design model has been build． Optimal control problem have been translated to nonlinear
programming problem Using Gauss pseudospectral methods． Nonlinear programming problem has been solved by SNOPT． The simulation
results show that Gauss pseudospectral methods can solve optimal control law problems of glide stage to cruise stage．

Key words: transitional section of missile, Gauss pseudospectral methods, optimal control, SNOPT software package
