英文摘要	This paper presents an implementation of control system of position actuators in LAMOST. Performance of actuators has been tested in laboratory. The resolution of actuators is less than 5nm. The whole control system has been successfully realized in LAMOST MB pre-segmented experiment. The control system of position actuator adopts distributed-and-centralized mode. Displacement RMS error of the control system (including actuator and electrical control) is less than 50nm.
