AbstractA multivariable non-interacting control technique has been applied to the configuration control of single-null divertor plasmas in JT-60U. Strong interactions between the controls of the plasma current and the plasma horizontal position—which inevitably occur during their independent control, owing to large inductive coupling between the ohmic heating coil and vertical magnetic field coil—have been drastically suppressed by adopting the non-interacting control. The multivariable non-interacting control technique is a general method and can be applied to any tokamak machine, including tokamak fusion reactors such as ITER. Poloidal field coil currents and voltages required for configuration control in ITER-CDA have been investigated using this control algorithm.
