Abstract

In order to improve the synchronization, flexibility and expansibility of the plasma control on HT-7, a new plasma control system (HT-7 PCS) was constructed. The HT-7 PCS was based on a real-time Linux cluster with a well-defined, robust and flexible software infrastructure which was adapted from DIII-D PCS. In this paper, the hardware structure and system customization details for HT-7 PCS are reported. The plasma position and current control, plasma density control and off-normal event detection, which were realized in separated systems originally, have been integrated and implemented in such HT-7 PCS. All these control algorithms have been successfully validated in the last several HT-7 experiment campaigns. Good control performance has been achieved and the experiment results are discussed in the paper.

► The hardware and software structure of the new HT-7 plasma control system (HT-7 PCS) is reported. ► All original systems were integrated in the new HT-7 PCS. And the implementation details of the control algorithms are given in the paper. ► Different from EAST PCS, the AC operation mode is realized in HT-7 PCS. ► The experiment results are discussed. Good control performance has been obtained.
