Description

Highlights: • A MIMO decoupling controller has been designed for EAST shape control. • Tokamak simulation code (TSC) has been used to verify this MIMO controller. • This method is used in EAST experiment. • Preliminary results show the potential of this approach for the EAST plasma shape control systems. - Abstract: The efficient and safe operation of large fusion devices relies on plasma configuration inside the vacuum chamber. Due to EAST PF coils distribution, it is difficult to physical decouple plasma control parameters and poloidal field (PF) coils current. In this paper, we present a MIMO decoupling controller aimed to overcome the intrinsic limitations of simpler SISO controller, this new controller has been validated by means of the Tokamak Simulation Code (TSC) and implemented on the EAST tokamak. Preliminary results show the potential of this approach for the EAST plasma shape control systems.
