FDI Meets Plant’s Device Integration Needs

The future is digital, and digital should be intuitive and easy to use. Some users of 4–20 mA/HART, Foundation Fieldbus, and Profibus devices have to grapple with two sets of files to integrate their devices: electronic device description (EDD) files and device type manager (DTM) software drivers. Field device integration (FDI) is a new device […]

Fed-Batch Process for Chili

What are the Inherent Differences in the Performance of Pure Batch, Fed-Batch and Continuous Reactors?

In pure batch operations, changes in feed conditions, disturbances, or demand show up as changes in the profile of key process variables. For a bioreactor, variability in the seed culture, indeterminacy of cell response and changes in the demand for air, substrate (e.g. glucose), and reagent cause the variation in the batch profile for dissolved […]

Knowledge is power

Leverage New Knowledge to Avoid Being Blindsided

The idea that knowledge is power, coupled with the massive amount of information available to all of us today, should mean everyone should be powerful. Never before in human history has so much information been available. Movable type and the printing press in 15th-century Europe is generally considered the first “information revolution,” followed by the […]

An Overview of the Control Loops for Batch, Fed-Batch and Continuous Reactors

Nearly all reactors have temperature and pressure control since these affect reaction rate. Concentration control is desirable but depends upon the feasibility, accuracy, and reliability of analyzers and inferential measurements. For at-line analyzers, there is the additional consideration of the dead time added to the loop. To date offline analyzers have only been used to […]

Static Feedback Stabilization of Nonlinear Systems

Abstract: This paper considers a single sensor and single actuator approach to the static feedback stabilization of nonlinear systems. This is essentially a remote control problem that is present in many engineering applications. The proposed method solves this problem that is less expensive to implement and more reliable in practice. Significant results are obtained on […]
