Abstract

A plasma equilibrium control simulator has been developed to simulate the control of plasma position and shape as well as plasma current IP. The simulator consists of an equilibrium calculation component and a controller component. The plasma position, shape, and IP are obtained as a result of an equilibrium calculation under the specified poloidal field coil current. The control simulator enables simulation of the control of the position, shape, and IP using the isoflux technique, and it optimizes the control logic of the coil current in JT-60SA. The plasma equilibrium control is simulated during IP ramp-up. The controllability of the last closed flux surface is also validated during IP flat-top.
