Pre-Results of the Real-Time ODIN Validation on MARTe Using Plasma Linearized Model in FTU Tokamak

“…7 the MARTe ODIN Test System is shown. Several signals are produced by the WaveFormGAM, the Test Probe signals and an arbitrary and tabled guess for w (for example a conic surface centered in R 0 and monotonically decreasing or increasing along h and constant alongx) [3][4][5]. Next, the moments are calculated (using MomentsGAM) and a least squares approximation which fits the magnetic measurements is performed by the ODINGAM.…”

“…In previous researches [3][4][5] we have shown the real-time reconstruction of plasma equilibrium using the multi-polar moments. In this paper we are interested in validating the real-time ODIN on MARTe modular architecture using plasma linearized model in FTU tokamak.…”

“…As we proposed in [4], the idea is to split over those threads the independent sine and cosine parts of the calculation or to separate them out in different sections of the mesh, letting the main thread merge the results when needed. Once the equilibrium is reached, the system could send the output data to the main feedback controller performing shape and position regulation (using a real-time network such as RTNET [5] or using DACs and ADCs).…”
