Abstract

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 de- signed 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.
