Distributed plantwide process control based on dissipativity

This paper presents some recent results on distributed plantwide control based on the concept of dissipativity. The plantwide process is modelled as a network of process units interconnected with physical mass and energy flows. By using dynamic supply rates, the plantwide stability and performance conditions transformed into the dissipativity conditions that each controller needs to satisfy. Developments in plantwide operability analysis, distributed model predictive control, analysis of multi-time scale plantwide process dynamics and their extensions to nonlinear systems are discussed.
