以电视制导为背景,就框架式导引头控制技术进行了研究。阐述了现有模拟式框架导引头稳定跟踪平台的优缺点,分析了导引头稳定跟踪平台的设计方案及组成,通过对模拟式框架导引头稳定跟踪平台和数字式框架导引头稳定跟踪平台的比较,找出了二者的优缺点。在建立系统的数学模型基础上,利用MATLAB计算了根轨迹、幅值裕量、相角裕量、超调量和过渡时间,求解了校正函数,通过串联校正来使系统满足初始要求。在控制器的硬件设计上,选择了TMS320F2812信号处理器,说明了TPS767D318电源芯片和JTAG接口的引脚连接,同时,在基于F007集成运算放大器的基础上设计了由0～5V转变为0～3V的信号采样电路。

Based on the background of TV guidance,the paper researched on the control technique of frame-type seeker.In the paper,it expounded the advantages and drawbacks of analog frame seeker platform of stable tracking,analyzed the design scheme and composition of stable tracking platform of the seeker.By means of the comparison of stable tracking platform between analog and digital frame seeker,it found the advantages and drawbacks of the both.On the basis of system math modeling,by use of MATLAB it computed the root trajectory,margin of amplitude and phase,overshoot and transition time,and solved the revised function to make system satisfy initial demand of the system through series correcting.For the aspects of controller hardware design,it selected TMS320F2812 signal processor to explain the pin connection between TPS767D318 power supply chip and JTAG interface.At the same time,based on the integrated operational amplifier F007,it designed the signal sampling circuit transformed from 0～5V to 0～3V.
