The port-Hamiltonian formulation is a promising approach for modelling and control of the multiphysics tokamak system. This method is based on the explicit representation of all power exchanges between the multi-domain subsystems. Hence, it allows to consider subsystems with complex dynamics, including non-linear behaviour or spatially distributed phenomena.
In this work, a port-Hamiltonian model has been derived for the Thermo-Magneto-HydroDynamics (TMHD) of plasmas in tokamaks, including Maxwell field equations as well as energy balance equations in different domains. A controlled model is obtained, using the geometric spatial reduction methodology which aims to preserve, throughout the reduction, both the symplecticity of the interconnection structure and the important physical quantities of the original system. Taking advantage of these conserved structure and quantities, a general controller named IDA-PBC (Interconnection and Damping Assignment – Passivity Based Control) is proposed. It is applied to the TMHD tokamak plasma system for the plasma current profile control. The method has been validated both on simulation and real time tests on TCV.
