摘　　要：文中介绍以DSP芯片TMS320LF2407A为核心的连续变焦镜头控制系统的设计,主要包括变焦距镜头的变焦原理、控制系统硬件电路的构成、电机控制电路的设计以及软件结构。实验结果表明,这种变焦镜头控制系统实时性好、系统体积小、可靠性高,最大焦距控制误差小于2%。配合光电捕获跟踪(ATP)系统可实现对运动目标的实时变焦跟踪。The design of zoom lens control system based on TMS320LF2407A is introduced in this paper. It mainly consists of the theory of zoom lens, the hardware circuit of control system, the control circuit of motors and the structure of software. The practice of project shows that this zoom lens control system has advantages of well real-time, small system cubage and high reliability. The maximum error of zoom control is less than 2%. If cooperated with ATP system, it can track the moving target real timely.
