In order to implement high precise control of turntable

a digital control system for turntables is designed.The coutrol system takes microprocessor MSP430 as control core

use modularization design idea and open-ended structure form

design hardware circuits of turntables control system and discuss its functions and principle.Using VC + + 6.0 as development environment

design software structure of upper computer;using IAR EW 5.0 as development environment

design software structure of lower computer of control system.In order to validate performance of control system

control experiment is carried out

results show that control effect of system is good and achieves expected effect.
