In recent years, tokamak plasma equilibrium control of position, shape, current profile, etc., has been recognized to be very sensitive to the energy confinement performance of a plasma. In addition, it is necessary to effectively control plasma (separatrix line)-wall clearances to prevent the in-vessel structures from being damaged by high-energy plasma particles. To satisfy such requirements for plasma equilibrium control, precise reproduction of the entire plasma shape and current profile is one of the most essential issues in fusion experimental devices. This report describes in detail the current status of plasma equilibrium analyses mainly using magnetic measurements in tokamak experiments. In particular, methods that have been proposed for this analysis are explained in terms of applied mathematics and their practical use in the real-time control of plasma and in the off-line analysis of experiment data.
