Integration of Corsica and Mathworks Simulink for Simulation of Tokamak Plasma Control System Operations

Using an RPC interface that allows us to do process-to-process communication, we are integrating the Corsica equilibrium and transport code into Mathworks Simulink for simulation of tokamak plasma control system operations. We have done initial testing using a simple vertical-position-control DIII-D simulation and are now in the process of defining the plasma model interface and modifying Corsica to implement that interface. The interface will be as general as possible - machine parameters will be driven from Simulink - but balanced against the need to maintain a standalone Corsica, in particular, the free-boundary equilibrium solutions. The objective is code verification by benchmarking open-loop Corsica evolution with DIII-D experimental data*. Corsica will then be used as a plasma model in Simulink for closed-loop DIII-D and ITER scenario simulations.\break \break * Leuer, J.A., et al, Proc. 20th IEEE Symp. on Fus.
