Simulation of ITER Control Scenarios with Corsica Plasma Models

We are developing capabilities for using the Corsica equilibrium and transport code as the nonlinear plasma model, and synthetic diagnostic set, to explore ITER state-space controller techniques. The state-space controllers are implemented in the Mathworks Matlab/Simulink environment. Corsica is coupled to Simulink via remote procedure call (rpc) allowing Simulink to access the Corsica internal database. The Simulink state-space controllers use the rpc interface to communicate active control coil currents to Corsica which calculates and updates the equilibria and transport for free-boundary plasma evolution. When a time step is complete, Simulink retrieves the feedback gap, current, and flux data through the same rpc access. The rpc interface allows the Corsica plasma simulations to be run on a remote high performance Linux cluster while the Simulink graphical interface is run on the local desktop. We will report on the progress in simulating vertical stabilization , and current and shape control experiments.
