攻击地面固定目标寻的导弹的一体化制导与控制(英文)

Integrated Guidance and Control of Homing Missiles Against Ground Fixed Targets

考虑了攻击地面固定目标的寻的导弹俯仰通道的一体化制导与控制系统设计问题。首先,建立了导弹俯仰通道的一体化制导与控制系统模型。然后,将系统模型转化为标准形式并结合滑模控制理论设计了自适应非线性反馈控制器,该控制器保证了导弹能以期望的末端姿态角精确击中目标。同时,系统的稳定性也得到了证明。最后,导弹的非线性数值仿真验证了所提的导弹一体化制导与控制策略的有效性。

This paper presents a scheme of integrated guidance and autopilot design for homing missiles against ground fixed targets. An integrated guidance and control model in the pitch plane is formulated and further changed into a normal form by nonlinear coordinate transformation. By adopting the sliding mode control approach, an adaptive nonlinear control law of the system is designed so that the missile can hit the target accurately with a desired impact attitude angle. The stability analysis of the closed-loop system is also conducted. The numerical simulation has confirmed the usefulness of the proposed design scheme.
