Simulation suite for plasma magnetic control at EAST tokamak

Abstract In view of ITER operations, many experiments are being conducted on the EAST tokamak. In particular, new magnetic control approaches are being developed and need to be tested. In order to design and test a plasma current, position and shape control, an accurate modeling of EAST static equilibria and dynamic plasma evolution is required. Hence, a suite of simulation tools has been developed for the reconstruction of plasma equilibria, the generation of plasma linearized models and for the closed loop testing of magnetic control algorithms. These tools are meant to assess the reliability of such equilibria and models, in order to provide a robust tool for the purposes of control design.
