Plasma control system is one of the critical systems in fusion experiments, responsible for real-time feedback control of various plasma parameters. The existing independently developed plasma control system adopts a component-based model, with its core control function implemented by executing various plasma control algorithms through algorithm components. It requires preset parameters of the graphical interface editing algorithm and will manage them. Therefore, the graphical interface is implemented by using PyQt5, and a parameter configuration component is developed to process parameter storage and retrieval. Data transmission between them is achieved through publish/subscribe messaging mechanism. Extensible markup language is used to define the preset algorithm parameter information, so as to decouple the user interface and control algorithm. The parameter data structure is uniformly defined through interface description language, and MySQL database is designed to store historical parameter data. Data communication is completed based on publish/subscribe messaging mechanism.
