Direct Measurement of the Plasma Equilibrium Response to the Poloidal Field Changes and H Controller tests in TCV
The control ITER provides several challenges which can be met using existing techniques for the design of modern controllers. The specific case of the control of the Poloidal field (PF) system has solicited considerable interest. One feature of the design of such controllers is their dependence on a sufficiently accurate model of the full system under control. To this end, experiments have been performed on the TCV tokamak to validate one plasma equilibrium response model, the CREATE-L model. Using a new technique, the open loop response of TCV has been directly measured in the frequency domain. These experimental results compare well with the CREATE-L model. This model was subsequently used to design a PF system controller, using methods proposed during the ITER EDA and the first test on TCV has been successful.
