摘要

Model predictive control technology has brought huge benefit in the refining/petrochemical industry and starts to attract attention of other process industries. However, sustainability is a big challenge in MPC applications due to its technical difficulties and high cost in human resources. In order to considerably reduce the difficulties and costs of MPC deployment and maintenance, we introduce an adaptive MPC controller. The adaptive MPC consists of three modules: an MPC control module, an online identification module and a control monitor module. The three modules work together coherently in real-time. During MPC commissioning, the online identification module and the MPC control module work together and perform various steps in MPC implementation automatically. When the MPC controller is online, the control monitor module continuously monitors the MPC performance and model quality. When control performance degradation and considerable model error are detected, monitor module will start the maintenance by activating the online identification module. The identification module will re-identify the model and replace the old model. Most of the steps can be done automatically under the supervision of the operator. The scarce control expert is only needed in controller design. A prototype of the adaptive MPC controller has applied successfully to two PTA units and the results will be reported.
