Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Systematic, multiple initial value simulations are performed for a toroidal plasma using the recently updated MARS-F code in order to understand how the resistive wall mode (RWM) can be feedback controlled in the presence of control coil voltage saturation and/or sensor noise. The former renders the control nonlinear, thus generally requiring initial value computations for toroidal plasmas. This numerical study complements and confirms the key results from a previously analytic investigation of the RWM feedback with power saturation for a cylindrical plasma [Li et al., Physics of Plasmas, Vol. 19, 012502 (2012)]. Moreover, simulation results reveal a linear trend between the maximum tolerable sensor noise level and the degree of relaxing the control coil voltage saturation requirement, up to a certain level of noise, corresponding to a noise-to-signal ratio of about 25%. Beyond this level, further relaxing the control voltage saturation limit does not lead to increased sensor noise tolerance for the RWM stabilization.
