Real-Time Data Acquisition and Processing
Feedback Control system for plasma equilibrium in fusion research devices
The FTU feedback control system is based on two main subsystems: the Magnetic
Measurement System (MMS) and the Position and Plasma Current Regulation System.
The first subsystem is in charge of the analog-digital acquisition and the
elaboration of the measurements to calculate the magnetic flux distribution
and plasma position on vertical and horizontal axis. Moreover plasma position
displacements with respect to the pre-programmed values are calculated and
given in input to the second subsystem. This implements four PID digital
controllers to give the current references for the electrical power generators.
The whole digital controller has a total control cycle time < 0.5 ms.
