摘　　要：分析了导引头伺服系统的结构及其预置、稳定、搜索和跟踪等回路的功能。设计了基于双DSP结构的导引头伺服系统控制器,以实现导引头的通信、扰动隔离以及目标跟踪等功能,介绍了其硬件与软件实现方法。分析了导引头伺服系统的扰动隔离与目标跟踪原理,并以方位轴稳定回路为例,提出了基于dSPACE半实物仿真系统的数字控制器设计方法。扰动隔离仿真与目标跟踪试验结果表明:所设计的导引头数字控制系统具有较高精度,基本满足导引头的扰动隔离与目标跟踪功能。The structure of seeker servo system and the function of its servo loop including locking, stabilization, searching and tracking were analyzed. Based on the structure of dual DSP, a controller for seeker control system was designed in order to realize the function of communication, disturbance isolation and target tracking. And the hardware configuration and software structure were introduced. The theory of disturbance isolation and target tracking of seeker servo system was analyzed. A method for designing a digital controller based on dSPACE hardware-in-the-loop simulation system was proposed by designing a controller for yawing stabilization loop. Experimental results of disturbance isolation and target tracking show that the digital control system for seeker designed in this paper has good performance, and can satisfy the requirements of disturbance isolation and target tracking function of seeker.
