| Abstract: | In order to realize real-time and precise controlling plasma during the experiment of HT-7 tokomak, this paper made use of the parallel system of multi-processors, and designed the attribute and CPU affinity of the two threads in one process. It actualized the feedback control of poloidal field control system, which achieved the goal of real-time control in 1ms at HT-7 tokomak, at the same time obtained the position of plasma by parallel computing. |
