J-TEXT偏滤器电源系统设计为并联连接的12脉冲整流器，由100 MVA脉冲发生器单元供电。为了实现鲁棒的电流反馈控制，需要高性能的实时控制系统，新的控制系统采用了功能更强大的软件框架J-TEXT实时框架（JRTF）。JRTF是一个灵活的实时软件框架，专为实现实时控制系统而设计。JRTF应用程序包含各种应用程序块（AB），它们执行特定的功能，如反馈计算和保护。JRTF与ITER标准PFC（工厂快速控制器）硬件和ITER CODAC（控制、数据访问和通信）核心软件兼容，因此可以通过任何基于EPICS的控制系统进行监控和配置。新的控制系统硬件升级为标准的ITER快速控制器，比以前的控制器速度快、可靠性高，是JRTF的首次应用，运行结果表明新的控制系统运行正常、稳定。为J-TEXT中的实时控制方案提供了一个实例，也可应用于其他融合设备。
The J-TEXT divertor power supply system is designed as a parallel connection, 12-pulse rectifier which is powered by a 100 MVA pulse generator unit. To achieve robust current feedback control, high performance real-time control system is required.The new control system adopts a more powerful software framework named J-TEXT real-time framework (JRTF). JRTF is a flexible real-time software framework designed for the implementation of real-time control systems. A JRTF application contains various Application Blocks (AB) which execute specific functions such as feedback computing and protection. JRTF is compatible with ITER standard PFC (Plant Fast Controller) hardware and ITER CODAC (Control, Data Access and Communication) Core software, so it can be monitored and configured by any EPICS based control system. The hardware of the new control system is upgraded to standard ITER fast controller which are much faster and more reliable than former controllers.This control system is the first application of JRTF, and the result shows that the new control system is running properly and stably. It provides an instance for real-time control schemes in J-TEXT, and it may also be applicable to other fusion devices.
