Abstract

We briefly summarize a supposedly efficient novel method for measuring the external plasma response as applied to the inherently unstable reversed-field pinch EXTRAP T2R. The set of parameters estimated with this particular method is then harvested and fed as input to a discrete-time fixed-order fast Fourier transform decoupled multi-input-multi-output controller synthesis. The thus reconfigured feedback system is implemented and experimentally tested on the real plant T2R. A particular and intended behaviour is observed, it seems, from these first- deployment results.
