Abstract :
A multivariable electromagnetic model for the active control of resistive wall modes in RFP devices was developed. It accounts for the dynamic behaviour of both the saddle coil currents and the plasma modes. Side-bands effects due to the finite numbers of active coils and sensors are properly considered. First simulations of closed loop stabilization were successfully performed with reference to the EXTRAP-T2R machine.
