A predictive study on the plasma current and position control was carried out byapplying TSC to the EAST experiments with a plasma control system (PCS). Good agreementwas achieved between predicted and experimental results in the plasma current, major radius,minor radius, elongation and plasma electron density, etc., which indicates that TSC has highpredictability and reliability.
