This paper presents control system design for plasma containment in Tokamak fusion reactors. A mathematical plant model of plasma motion dynamics is derived by considering circuit dynamics of the control coils and eddy current models. So as to design a low order controller with numerical reliability, we have applied two approximation methods, singular perturbation and truncation, to the original plant model. The stabilizing controller is designed for the approximated plant model by standard H_∞ control method to achieve the robustness against disturbances and low voltage control. It is shown in simulation study that the designed reduced order controller works well for the original plant model and satisfies low control writage of the coils.
