Abstract: This paper proposes an approach aimed at avoiding or mitigating the
consequences of a plasma disruption in a tokamak. The control strategy is based
on a Disruption Predictive Control (DPC) where the use of a set of disruption
predictors could allow actively modification of some plasma parameters when a
disruption warning is issued. The DPC approach requires the continuous
monitoring of various plasma performance indicators, which play the role of
disruption precursors. The active control is based on the availability of
magnetic and nonmagnetic plasma parameter response models as well as
multivariable control algorithms and architectures.
