研究了半捷联末制导系统中捷联天线稳定系统的设计原理和控制算法。首先分析了捷联稳定和陀螺稳定的本质区别与联系；然后基于弹体、导引头、天线的三维运动关系，提出了一种新型捷联天线稳定系统控制方案。使用框架角测量和惯导信息重构天线的绝对空间运动信息，并采用角速度补偿方法和数学稳定平台实现导引头天线的间接稳定，能够解决导引头在纯稳定和目标跟踪两种工作模式下的天线控制问题。最后通过数学仿真验证了所提方法的有效性。

The design principle and control algorithms for strap-down antenna stabilization system of a seekers tracking system were studied.First,the essential difference and similarity between strap-down stabilizing method and rate-gyro method was discussed.Then,a new design scheme of strap-down antenna stabilization system was proposed based on the analysis to 3D movement relationship of missile body,seeker,and antenna.The measurement of seeker gimbals angle and missile INS information were used to reconstruct the absolute angular-rate imformation of antenna.And the stabilization of seeker antenna was implemented by using angular-rate compensation method and a mathematical stabilization platform.The proposed scheme was adaptable to the seekers antenna control applications both in pure stable mode and in target tracking mode.The effectiveness of the method was verified through computer simulations of an actual seekers antenna servo control system.
