An integrated plasma profile control strategy is being developed for extrapolating present-day advanced tokamak (AT) scenarios to steady state operation. The approach is based on semi- empirical (grey-box) modeling. It was initially explored on JET, for current profile control only. The present paper deals with the generalization of this strategy to simultaneous magnetic and kinetic control. The system identification algorithms take advantage of the large ratio between the magnetic and thermal diffusion time scales and have been recently applied, in their full version, to both JT-60U and DIII-D data. This provides, for control purposes, a readily available alternative to first-principle plasma modeling.
