Abstract
The main reflector of FAST consists of about 1800 elementary units. Each unit has threeadjustable supports to fix its position, and its position is adjusted by means of mechanical actuators.According to the radio source position at any given time, all the actuators are continuously adjustedto form a proper paraboloid in real time during the course of the observation. The basic requirementsof such a control system are discussed. A fieldbus control system based on LonWorks technology issuggested to control all 1800 actuators. The main advantages of this distributed control system areits reliability, flexibility, efficiency and economics.
