Abstract

Abstract: An iterative learning model predictive control(ILMPC) technique is applied to a class of continuous/batch processes.Such processes are characterized by the operations of batch processes generating periodic strong disturbances to the continuous processes and traditional regulatory controllers are unable to eliminate these periodic disturbances.ILMPC integrates the feature of iterative learning control(ILC) handling repetitive signal and the flexibility of model predictive control(MPC).By on-line monitoring the operation status of batch processes,an event-driven iterative learning algorithm for batch repetitive disturbances is initiated and the soft constraints are adjusted timely as the feasible region is away from the desired operating zone.The results of an industrial application show that the proposed ILMPC method is effective for a class of continuous/batch processes.

Key words: continuous/batch process, model predictive control, event monitoring, iterative learning, soft constraint
