Description
HL-2M is a medium-size tokamak constructed by Southwestern Institute of Physics (SWIP) in China. The first plasma has been successfully obtained in 2020 by using a plasma control system (PCS) based on Labview RT. In order to get better plasma control performance, a new PCS based on the software framework of DIII-D PCS has been proposed.
There are two concerns about realizing the PCS. First, real-time performance of PCS needs to be guaranteed. Second, many interfaces should be adopted for the HL-2M existing system. The proposed PCS is deployed on a Linux cluster with two servers, one is the non-real time server for message and waveform, the other is the real-time server with a D-TACQ196 DAQ card and two reflection memory(RFM) cards. The real-time operating system has been upgraded and optimized to improve real-time performance. Millions of testing results indicate that the jitter time of the system is less than
In the next phase, more control algorithms will be integrated and more tests will be carried out to verify system reliability.
