Abstract
First results from a numerical test of dynamic chaos control for the reversed-field pinch are presented. A control scheme, using a control signal in the form of a small time continuous perturbation, is implemented into a magnetohydrodynamic simulation code. The control signal, constituting the difference between a periodic external signal and the actual toroidally applied electric field, multiplied by an adjustable weight factor, is added to an existing code equation. This equation determines the loop voltage for a desired plasma current, and would correspond to modulations of the applied loop voltage in an experiment. The main effect of the dynamic control on the dynamics of the reversed-field pinch is an increase in the magnetic helicity with an unchanged value of the magnetic energy. The helicity increases in a stepwise manner, and occurs when the loop voltage undergoes a π phase shift.
