Description

During the start-up regime of the IBR-2M power fluctuations appear, which
the AR system dampens. Their origin is not completely clear, however it
is known that the major reactivity sources are from design - respectively
the OPO and DPO reflectors (axial fluctuations towards the active zone and
their relative phase of intersecting each other facing the center of the
active zone).
A neuromorphic solution is sought to anticipate (5-10 s) such fluctuations.
I present encouraging preliminary results obtained with a Non-linear
Autoregressive Exogenous neural network, the main features of the
fluctuations being anticipatable.
