“…A control system framework is needed to make the development of the control system a manageable task. The experimental physics and industrial control system (EPICS) framework is the most widely used control system framework [76,77]. It was widely accepted by the accelerator community as well as chosen by ITER.…”

In order to meet the stringent requirements of fusion power supply for large-scale fusion devices, the J-TEXT engineering team has carried out key technology research and applications in several important directions of fusion power supply. This article presents the advances made by the J-TEXT engineering team in recent years in the following areas: (1) high-voltage power supply for auxiliary heating system; (2) breakdown protection device for auxiliary heating power supply; (3) magnetic field compatibility; (4) high-voltage pulsed power supply for field reversed configuration; (5) large physics experimental facility control system. The research backgrounds, technical progress, test results, applications, summaries and prospects are described in detail in each part. These innovative research results and valuable engineering experience can promote the progress of fusion power supply technology, and also lay a foundation for the development of power supplies with higher parameters in the future.

“…The operation and control units of KSTAR tokamak are activated by a variety of local subsystems and different platforms. Accordingly, Experimental Physics and Industrial Control System (EPICS) is used to provide a centralized control unit from heterogeneous systems [17,18]. In KSTAR tokamak, the monitoring system is used to investigate tokamak performance and different sensors for temperature, plasma replacement etc.…”

The aim of this paper is design and implementation of an up-to-date control room. The previous control room had a lot of constraints and it was not apposite to the sophisticated diagnostic systems as well as to the modern control and multivariable systems. Although it provided the best output for the considered experiments and implementing offline algorithms among all similar plants, it needed to be developed to provide more capability for complex algorithm mechanisms and this work introduces our efforts in this area. Accordingly, four leading systems were designed and implemented, including real-time control system, online Data Acquisition System (DAS), offline DAS, monitoring and data transmission system.In the control system, three real-time control modules were established based on Digital Signal Processor (DSP). Thanks to them, implementation of the classic and linear and nonlinear intelligent controllers was possible to control the plasma position and its elongation. Also, online DAS was constructed in two modules. Using them, voltages and currents of charge for the capacitor banks and pressure of different parts in vacuum vessel were measured and monitored. Likewise, by realtime processing of the online data, the safety protocol of plant performance was accomplished. In addition, the offline DAS was organized in 13 modules based on Field Programmable Gate Array (FPGA). This system can be used for gathering all diagnostic, control, and performance data in 156 channels. Data transmission system and storing mechanism in the server was provided by data transmitting network and MDSplus standard protocol. Moreover, monitoring software was designed so that it could display the required plots for physical analyses. Taking everything into account, this new platform can improve the quality and quantity of research activities in plasma physics for Damavand tokamak.

“…In addition, the PCS also needs to provide real-time monitoring to ensure the robustness of the system and other functions. The plasma control system in KTX is based on the EPICS (Experimental Physics and Industrial Control System) [6] framework and a real-time Linux cluster with a well-defined, robust and flexible software infrastructure which was adapted from the DIII-D (Doublet III-D) PCS [7−9] . The KTX PCS is designed by ASIPP (Institute of Plasma Physics, Chinese Academy of Sciences), and needs to meet the requirements of real-time, stability, flexibility and other performance requirements in plasma discharge experiments.…”

KTX (Keda Torus for eXperiment) is a new reversed field pinch device. The KTX plasma control system (PCS) can provide real-time, stable, flexible plasma control which is designed by ASIPP (Institute of Plasma Physics, Chinese Academy of Sciences), based on the Linux cluster system and EPICS (Experimental Physics and Industrial Control System) framework, and developed from DIII-D (Doublet III-D) PCS. The control of the equilibrium field in KTX uses a PID (Proportional-Integral-Derivative) feedback controller. The control of the gas injection is an open loop control.The plasma control simulation system is one part of the plasma control system, which is used to test the plasma control algorithm if it is revised and updated. The KTX PCS has been successfully tested using HT-7 (Hefei Torus 7) experiment data in simulation mode. In the next phase, an error field feedback control and KTX simulator will be added to the KTX PCS, and the KTX PCS will be applied in experiments in the future.
