摘要:

针对空地导弹的制导控制一体化设计问题,给出了基于扩张状态观测器的动态逆设计方法。建立了导弹纵向通道的制导控制一体化模型,使用动态逆方法对导弹进行了制导控制一体化设计。为克服动态逆方法的缺陷,将制导控制系统的建模误差和未知扰动皆视为不确定性,设计了扩张状态观测器并对其进行估计。仿真结果表明,该方法具有较高的制导控制精度,并满足攻击角约束。

Abstract:

The dynamic inverse method based on extended state observer is presented for the problem of air-to-ground missile’s integrated guidance and control. With a view to maneuver of ground targets, the integrated guidance and control model is constituted. According to this model, the design method of integrated guidance and control is given by using dynamic inverse. In order to overcome the defect of the dynamic inverse method, the uncertainty of guidance and control systems is estimated based on the extended state observer. Simulation results show that this integrated guidance and control method can implement efficiently attack constraint mission for missiles as well as preferable guidance and control precision.
