Distributed Process Control Using Dissipativity Theory
Abstract
This talk will give an overview of a non-cooperative distributed control approach (including distributed model predictive control) based on the dissipativity theory. Complex process plants increasingly appear in modern chemical industry due to the considerable economic efficiency that complex and interactive process designs can offer. Due to the wide use of material recycles and heat integration, there are severe interactions between process units, which profoundly alter and complicate plantwide process dynamics. In this approach, a plantwide process is explicitly modelled as a network of interconnected process units (with both physical mass and energy flow and information flow) and controlled by a network of autonomous controllers. The plant-wide process and distributed control system are represented as two interacting process and controller networks, with interaction effects captured by the dissipativity properties of subsystems and network topologies. The plant-wide stability and performance conditions are developed based on global dissipativity conditions, which in turn are translated into the dissipative trajectory conditions that each local MPC must satisfy. This approach is enabled by the use of dynamic supply rates in quadratic difference forms, which capture detailed dynamic system information. Extensions to contraction theory and data-based dissipativity theory will also be discussed.
