主要论述了基于FPGA的末制导雷达伺服系统设计。结合末制导雷达讨论其电机控制、二阶伺服系统性能和PID校正算法,利用VHDL语言设计,实现基于FPGA的方位步进电机开环定位控制和俯仰直流电机闭环速度控制的伺服系统。结合实际应用中遇到的问题,提出了基于"反馈控制"理论的有效的补偿算法,该算法提高了伺服系统的稳定性、快速性和精度。(Mainly discusses the design of terminal guidance radar servo system based on Field Programmable Gates Array(FPGA).It includes the system’s electric machine control,second-order servo system performance and PID correction algorithm based on Virtual Hardware Description Language(VHDL) on azimuth stepping motor open loop positioning control and pitch direct current electric machine closed loop speed control of the FPGA servo system.In allusion to some factual problems during its application,presents corresponding effective solutions based on traditional control theory "Feedback Control".The fact proves that these methods can greatly improve the stability,speediness and precision of the original servo system.Additionally,a basic algorithm which can be realized in a terminal guidance radar servo system is given)

在一些系统中，经常用到对触发信号延时一段时 间后，再对某些目标信号进行采集，通常这段延时要求 非常精确，还要做到范围可调，一般这种延时的最小时 间单位小于100ns。如果选用普通微控制器，延时系统的操作界面比较容易实现，但是靠软件延时得到结果的准确性较低。考虑到芯片功能、开发环境以及接口方便等问题，最终选用一片常用的AlteraSVCPLD EPM7128SLC3411]作为系统的核心控制部分，来实现 信号延时、输人设定、运行显示的功能。应用Veril- o苦2〕语言，在Altera的Quartus11WebEditio详3〕软件 环境下进行编程仿真，最后烧写芯片进行系统硬件测试 -err
