Abstract:  In order to support the research of the plasma divertor configuration experiment on J-TEXT, a real-time control framework was developed based on the LabVIEW programming language. On J-TEXT, the real-time control framework and the selection of the appropriate NI acquisition card and controller are used to build a single-null position auxiliary power supply-bias power control system for the divertor, and the power supply is tested. The results showed that the power supply can output a current of 2kA within a control period of 1ms, which meets the experimental requirements of the single-null configuration of divertor on J-TEXT. The development of this framework greatly improves the efficiency of building a real-time control system and enhances the readability and maintainability of the control program, providing a complete, simple and easy to expand and transplant real-time control framework for J-TEXT.
