摘要
Control of the vertical instability of the plasma in the SUNIST spherical tokamak is studied. A proportional-derivative （PD） position controller is employed in a control system which consists of a massless plasma, active coils and a passive conducting vessel. Stability conditions axe determined and the feedback control with different combinations of both active and passive coils, available on SUNIST, is emphasized. The simulation results are also discussed.
