Using a model to describe the plasma density response to the gas puff command, a gas simulation server （simserver） using MATLAB simulink tools and real time workshop was built up. Proper operation of the gas control algorithm was verified using this simserver. The simulation results suggested that the gas control can be applied in the next EAST campaign.展开更多

文摘In this paper, gas control on EAST in open and closed loop is discussed and its implementation into EASTPCS （plasma control system for the experimental advanced supercon- ducting tokamak） is introduced.
