The Large Sky Area Multi-Object Fiber Spectroscopic Telescope , LAMOST hereafter, will become an astronomical telescope with largest field of view and most efficient observation in 4-m aperture telescopes in the world by its completion in 2008. In June 2007, Small System for LAMOST was completed successfully. Small LAMOST is composed of mirror with aperture of 3 meter(effective aperture of 2 meter ),250 fibers one spectrograph two 4kx4k CCD camera tracking and controlling system. This paper presents the study in Small LAMOST. It comprises three main parts. First, it introduces the software design for the control system of Small LAMOST, including Mount tracking, Focal Plane tracking, GPS time ticking and time synchronization between computers, auto-guiding, etc. The design has proved correct and feasible. Second, it describes some technical solutions to the requirements of precision, real time and open architecture for Small LAMOST. Lastly, some experimental data and curves are given to show the tracking precision of Small LAMOST.
