Formalization for Optimal Feedback Control of Plasma Current and Position in a Tokamak

摘要

Simultaneous control of the plasma current and position in a tokamak is formalized to apply an optimal feedback rule. The optimal feedback rule is first explained. A physical model of the tokamak system is then modified to be combined with the feedback rule: A linearized state description is derived from circuit equations of plasma, air-core transformer coil and vertical field coil, with equilibrium equation. Possible extension of the method to a more complicated system is also described. (Atomindex citation 09:371971)
