Abstract
KSTAR experiments have been conducted aiming at establishing a real-time control system that uses multiple actuators (NBI and ECH) to control the plasma profiles (Te and q profiles) and validating an applied physics-based plasma profile response model. Toward establishing the multiple plasma profile control system, the control experiment of the electron temperature profile has been performed in KSTAR as a first step. Although the plasma profile control system was in the commissioning phase, the electron temperature was feedback controlled successfully in real-time while the normalized radial profile of electron temperature remained nearly constant. In the circumstance, the implemented physics-based response model was successfully validated against control experiments with a step variation on the control target and an application of multiple actuators. The robustness of the controller is examined against an external disturbance in which a static version of the control matrix was used.
