Abstract
The main objectives of this chapter are: to introduce a simplified model for the evolution of the boundary condition (2.16) involving the coupling between the LH power injected into the system and the total plasma current; to use this simplified model to explore the possible impact of these couplings on the stability of the interconnected system; to implement the control law, developed in Chap. 4, in simulation using the METIS code, part of the CRONOS suite of codes [2]; to simulate the effect of profile-reconstruction delays of 100 ms (based on the sampling time in [4]); to extend the control law developed in Chap. 4 in simulation using the RAPTOR code [9] for TCV scenarios.
