Asdex-upgrade Tokamak Emulator for Test of Control System and Shot Programme

to be conducted . Utilizing precise boundary conditions An emulation system is described which replaces the the most important internal states of the control software ASDEX-Upgrade tokamak device for controlled nuclear can be tested and verified . With this testing of the fusion as a data source and its discharge control system software togeth~'r with redundant systems, fail safe as a processing unit. The purpose of the system is to technique and other methods high reliability can be generate real time data which are either preprogrammed achieved. The use of backup systems for the conduct of or recorded from previously executed plasma the emulation tests allows software development to discharges, and to process them like the discharge proceed in parallel to the ASDEX-Upgrade physical control system would do. The real time emulation of both, fusion device and control system, allows enhanced flexibility in testing and analysing the software of the control loop. This development follows the trend towards safe control concepts for future reactor control systems.
