带多个弹道路径点约束的扩展MPSP制导方法

Guidance method by extended model predictive static programming with multiple way-points constraints

针对弹道导弹临近空间低弹道突防问题,对仅仅满足末端输出量约束的模型预测静态规划(MPSP)制导方法进行扩展,提出了带弹道路径点约束的扩展MPSP制导方法。通过在临近空间中段飞行弹道上设置一系列弹道路径点约束,依靠这种策略调节中段飞行弹道的形状,提高弹道导弹的机动突防能力。通过仿真对扩展MPSP制导方法的有效性进行验证,仿真结果表明扩展 MPSP制导方法能很好地满足临近空间中段低弹道飞行弹道路径点约束,弹道路径点处的角度偏差可控制在0.1°范围内,位移偏差可控制在1.0m范围内。

To solve the problem of low-trajectory penetration in near space of tactical ballistic missiles, an extended model predictive static programming (EMPSP) guidance method with trajectory way-points constraints is proposed. By setting a series of trajectory path constraints on the midcourse flight trajectory in near space, the shape of midcourse flight trajectory can be adjusted to improve the penetration capability of tactical ballistic missiles. Simulation results verify the effectiveness of the EMPSP guidance method and show that the proposed EMPSP guidance method can very satisfy midcourse flight low-trajectory way-points constraints in near space. The angular deviation can be controlled to within 0.1°, and the displacement deviation can be controlled to within 1.0 m at the trajectory way-point.
