摘要：

This paper describes the application of a nonlinear model-based control strategy in a real challenging process. A predictive controller based on a nonlinear model derived from physical relationships, mainly heat and mass balances, has been developed and commissioned in the inner triplet heat exchanger unit (IT-HXTU) of the large hadron collider (LHC) particle accelerator at European Center for Nuclear Research (CERN). The advanced regulation maintains the magnets temperature at about 1.9K. The development includes a constrained nonlinear state estimator with a receding horizon estimation procedure to improve the regulator predictions. (C) 2009 Elsevier Ltd. All rights reserved.
