The System is used for switching on power supplies according to given timing, checking their real condition with given operating parameters, providing negative feedback control command and excursive order after comparing with on­line measured plasma data to control the main plasma parameters. The main currents on HL-2A include plasma current Ip, the current in toroidal coil IT , the current in ohmic winding IW, the current in vertical field coils IV, the current in multi-pole coils IM

·The pre-programmed ‘passive’ electrical pulsed power control

· Active (feedback-enabled) real-time control

  1) Plasma current, position, shape real-time control.

  2)  Plasma density, temperature, pressure real-time control.
