Autotuning for Plantwide Control Systems
Typical chemical processes consist of many process units. Therefore, the success of the production depends a great deal on the smooth operation of all these units. As a result of stringent environmental regulation and economic consideration, today’s chemical plants tend to be highly integrated and interconnected. Moreover, the steady-state and dynamic behavior of these interconnected units differs significantly from individual units. Therefore, the problem of plantwide control becomes the operation and control of these interconnected process units. A typical interconnected process unit is the recycle system: process with material recycle.
