本文简单介绍了现有两种反辐射导弹(ARM)导引头随动系统，液压伺服随动系统和电动平台随动系统。在综合二者优点的基础上，设计了一种性能更优的捷联反辐射导弹(ARM)导引头随动系统。它将惯性姿态测量元件与载体捷联安装，系统采用经典的比例积分微分(PID)控制，伺服机构采用脉冲宽度调制( PWM)驱动的直流力矩电机，引导规律为比例导引。文中详细分析了该种方案的主要性能和特点，仿真表明所设计系统具有良好的性能。

Describes briefly two existing anti-radiation missile (ARM) seeker follow-up systems, viz. the hydraulic pressure servo ARM seeker follow-up system and eiectromotion ARM seeker follow-up system. On the basis of retaining their superiority, a new strapdown ARM seeker follow-up system with better per?formances was suggested. In this system the inertial measurement unit is fixed on the vehicle directly. It adopts the classical proportional integral differential control, witn its servomechanism adopting DC moment motor driven by pulse width modulation working on proportion guidance. The paper analyzed the perfor?mance and characteristics of the ARM seeker follow-up system in detail. Theoretical analysis and simulation show that the ARM seeker follow-up system inherits the excellence of the above two ARM seeker follow-up systems that the structure of the system is simple, and that the effect of the missile attitude movement to steady-state response of the ARM seeker follow-up system is eliminated with integral control. Simulation results also show that the designed system has good tracking performance.
