Development and Application of an Integrated MPC Technology

This work introduces an integrated MPC controller. The integrated 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; it can perform automatic controller commissioning and automatic controller maintenance. In 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. A prototype of the integrated MPC controller has applied successfully to two PTA units and the result will be reported.
