摘要：In this paper,a complete industrial validation of a recently published scheme for on-line adaptation of the control updating period in model predictive control is proposed.The industrial process that serves in the validation is a cryogenic refrigerator that is used to cool the supra-conductors involved in particle accelerators or experimental nuclear reactors.Two recently predicted features are validated:the first states that it is sometimes better to use less efficient (per iteration) optimizer if the lack of efficiency is over-compensated by an increase in the updating control frequency.The second is that for a given solver,it is worth monitoring the control updating period based on the on-line measured behavior of the cost function.
