Description
Ten years ago digital hardware offered for the first time the real time processing
power required for particle accelerators RF control (LLRF). This opened the
opportunity to implement control algorithms hardly realizable with analog
electronics like adaptive feed forward or exception handling.
In contrast to digital control used in automotive engineering, hi-fi and
telecommunication sector the data rates to be processed are much higher and the
latency has to be much shorter in digital LLRF. Compared to algorithms used in
these
sectors LLRF algorithms are in an initial state.
After a short overview some present LLRF algorithms like digital RF feed back, RF
feed-forward, cavity resonance control, exception handling and others will be
explained illustrative of implementations at the DESY TTF.
