Standards-based integration of advanced process control and optimization

October 28, 2018
Author(s)
Guodong Shao, Hasan Latif, Carla Martin, Peter O. Denno
Integration of process control with optimization is critical to Smart Manufacturing (SM). Oftentimes, however, the process control solutions from one vendor do not interoperate with the optimization solutions of another. Incompatibilities among the

Implementations of the Tennessee Eastman Process in Modelica

February 22, 2018
Author(s)
Carla Martin-Villalba, Alfonso Urquia, Guodong Shao
The Tennessee Eastman process is a typical industrial process that consists of five main process units: a two-phase reactor where an exothermic reaction occurs, a separator, a stripper, a compressor, and a mixer. This is a nonlinear open-loop unstable
