Abstract

New algorithms using a truncated singular value decomposition of a linearised model have been implemented in the JET control system.Using three heating and current drive actuators (LHCD,NBI,ICRH),successful control of the safety factor profile has been achieved in quasi steady state conditions where the loop voltage was small and a large fraction of the plasma current was carried by the bootstrap current.
