During the 2003-2004 experimental campaigns on JET, real-time control of radially distributed parameters, such as the current and electron temperature gradient profiles, was achieved for the first time. This was the initial step of an ongoing long-term research program which aims to ultimately develop integrated control of steady state advanced tokamak scenarios and Internal Transport Barriers (ITB). At this stage, and for the sake of simplicity, the controller was based on the static plasma response only and on an algorithm that minimises a weighted sum of least square integral errors between requested magnetic and kinetic profiles (known to be strongly coupled) and measured ones. Such an integrated strategy is particularly relevant to future fusion devices such as ITER where the Heating and Current Drive (H & CD) actuators will be limited while more controls will be needed for burning plasmas. In addition, some actuators will be less versatile than in present-day tokamaks, due to simple physics and/or technology considerations (antenna design, wave propagation, etc.). The approach newly developed at JET therefore aims to use the combination of H & CD/PF (Poloidal Field) systems and the experimentally deduced plasma couplings in the most efficient dynamic way to achieve a set of simultaneous tasks. The controller based on the static plasma response was successful in achieving the various targets that were aimed at, thus demonstrating the relevance of the coupled profiles approach. However, the control was not robust enough to rapid plasma events such as the spontaneous emergence of transient ITBs or MHD instabilities.
