摘　　要：光电经纬仪在对空中目标进行跟踪测量时,为了获得清晰的图像,提高作用距离,需要进行调焦。文中设计了基于MSP430F169单片机的调焦控制系统,采用步进电机作为执行机构,电位器作为位置测量元件,UP-4HB01B作为步进电机驱动芯片。定位控制实验结果证明:调焦控制系统最大误差为0.037 5 mm,平均误差为0.011 25 mm,均方误差为0.005 665 mm,能够满足调焦控制系统的要求。During the tracking measure process with thedolite, in order to achieve clear image and improve the effective work- ing distance,it is need to focus. This paper designed a focus controlling system based on MSP430F169. It used step motor to be carrying out machine, potentiometer to measure the position signal, and UP -4HB01B to drive the step motor. The system has the maximum error of 0. 037 5 mm,the average error is 0. 011 25 mm,and the square error is 0. 005 665 ram. These results fulfill the index of focus controlling system.
