Management of real time processes for plasma parameter optimization at ASDEX upgrade

Beyond optimization of position and shape control, producing high performance plasmas relies on precise and coordinated control of plasma parameters. This requires a universal platform, into which control algorithms can flexibly be integrated to adapt to interesting discharge scenarios. With the multitude of processes expected to be implemented, management of real time processes becomes crucial. In this paper we shall demonstrate how this issue is raised by the requirement specification of the controller and how it influences its design, implementation and operation
