Magnetic Sensorless Sensing of Plasma Position in the Superconducting Tokamak HT-7

【摘要】 <正> Magnetic sensorless sensing experiments of the plasma horizontal position have beencarried out in the superconducting tokamak HT-7. The horizontal position is calculated from thevertical field coil current and voltage without using signals of magnetic probes placed nearby aplasma. The calculations are focused on the ripple frequency component of the power supply.There is no drift problem with the time integration of magnetic probe signals. The error of thederived plasma position is lower than 2% of the plasma minor radius.更多还原
