Abstract :
In this paper, we report on the implementation and experimental test of an algorithm for computing feedforward coil current trajectories that can produce an approximately correct evolution of plasma shape, using a nonlinear online optimization method that maintains coil currents far from their limits. The voltage trajectory that produces these currents can be used as the feedforward component of plasma shape control when combined with a multivariable linear feedback control algorithm.
