摘要

本文针对雷达罩引起的制导问题,提出了一种带雷达罩误差补偿的寻的导弹综合制导与控制设计。首先,通过整合导弹动力学和导弹与地面目标在纵向运动上的啮合运动学,建立了带雷达罩误差补偿的综合制导与控制系统数学模型。其次,由于系统是一个具有不匹配不确定性的时变系统,因此通过非线性坐标变换将模型转换为正常形式。第三,采用滑模控制理论设计了系统的自适应控制规律,并对闭环系统的稳定性进行了检验。最后,仿真证明所提出的综合制导与控制方案能有效补偿雷达罩误差,确保对目标的命中摧毁攻击。

Adaptive control law based integrated guidance and control design for missile with the radome error compensation
This paper presents an integrated guidance and control design for the homing missiles with the radome error compensation to address the guidance problems caused by radome. Firstly, a mathematics model of the integrated guidance and control system with the compensation for the radome error is built by integrating the missile dynamics and the engagement kinematics between the missile and ground target on the longitudinal motion. Secondly, the model is transformed into a normal form by nonlinear coordinate transformation because the system is a time-varying system with mismatched uncertainties. Thirdly, an adaptive control law of the system is designed by adopting the sliding mode control theory, and the stability of the closed-loop system is also conducted. Finally, the simulation proves that the proposed integrated guidance and control scheme can effectively compensate for the radome error and ensure the hit-to-kill attack to the target.
