— The control of the ITER tokamak unstable vertical position is considered in the presence of actuator saturation. Linearised models of the ITER system all share the feature of a single unstable pole (attributable to the vertical instability) and a large number of stable poles. The aim of this work is to improve the existing controller in the sense of… (More)
The control of the current, position and shape of an elongated cross-section tokamak plasma is complicated by the so-called instability of the current vertical position. Linearized models all share the feature of a single unstable eigenmode, attributable to this vertical instability of the plasma equilibrium movement, and a large number of stable or… (More)
The control of tokamak fusion experiments is outlined with particular reference to the evolution of the control from primitive pre-programmed operation, through to feedback control of many parameters, finally developing advanced methods which are destined to optimise the performance of the tokamak plasma. Four examples of enhanced control of tokamak plasmas… (More)
