Process systems and inventory control

Abstract

Abstract A framework for modeling constraints on the dynamic behavior of systems obeying the laws of thermodynamics is discussed. These constraints induce dissipativity and we call a system obeying such constraints a process system. Passivity theory then shows that low‐dimensional macroscopic analysis can be used for control system design. The inputs and outputs converge to their set points and the state vector converges to a stationary passive state provided one exists. Several examples are developed to support the theory and an extension is proposed for systems with equipment constraints.
