A Unified Approach to Plant-wide Dissipative Model Predictive Control*

An approach to plant-wide model predictive control based on dissipativity theory is presented. Dissipativity theory facilitates the decomposition of the plant-wide system into interacting process and controller networks. The controller may take a decentralized, distributed or fully centralized structure without significantly changing the complexity of analysis. This approach to dissipativity based control is enabled by the use of dynamic supply rates as quadratic difference forms which capture more dynamic system information than constant supply rates and decrease the conservativeness of the approach. Plant-wide dissipativity properties ensure stability of the plant-wide system and minimum performance.
