摘　　要：恒星光干涉议定天镜的转动是用五相步进电机来驱动的，它需要的控制信号由软件实现。软件设计是控制系统中最困难的部分，尽可能地用软件实现硬件功能，不仅可以降低成本，更重要的是，便于更新及升级。在观测过程全自动化的前提下，着重提出了我国恒星光干涉议实验系统中定天镜子系统的软件设计方案。A software design for the servo system of two siderostats in the prototype of a stellarinterferometer has been described in this paper. In the writer's another paper[2], the servosystem was introduced and its functions were demonstrated. The software is written in theEPR0M of an 8098 chip, which includes the communication routine between 8098 and themain computer. The routines are for positioning and tracking. The block diagrams of theroutines as well as the conventional instruction codes for common use in the whole software of the interferometer are listed in this paper.
