Popis: In this work we explore the practical feasibility of using MPC for PCSC in the ITER tokamak, employing complexity reduction techniques and recently developed fast on-line quadratic programming (QP) optimization methods. A survey of the available QP methods suitable for the on-line solution of MPC optimization problems is given, with emphasis on first-order methods, which have been recently considered as prime candidates for fast online MPC control. Using a modification of the QP solver QPgen, a five-fold speed-up compared to the state-of-the-art commercial solver CPLEX was achieved, with peak computation times below 10 ms using a four-core Intel processor.
