Open-Loop vs. Closed-Loop So where exactly does open-loop end and closed-loop begin? The line seems clear for some systems, but muddy for others. How much feedback is enough to qualify?

Since about 2015, when Don Bartusiak, the then chief engineer at ExxonMobil Research & Engineering, publicly advocated for the development of a new, standards-based, open—yet secure—process control ...

The system is made up of three main pieces of hardware. The first part is the core (or server), which is essentially a Linux PC running an OSC (Open Sound Control) server.

Years before groups like the Open Process Automation Forum (OPAF) were attempting to build an open and secure control architecture, Bedrock Automation had already built it. Albert Rooyakkers, Bedrock ...

This method requires a more complex control scheme and is costlier to implement and maintain. Since closed-loop heating relies upon various components for precision feedback and optimized control, the ...

Apply feedback control laws to stabilize systems and achieve performance goals. Control systems are ubiquitous among many science and engineering disciplines. Learn topics in modeling, analysis, ...

Proper choice of feedback control strategy is not the only consideration in the feedback fuel delivery systems. Open loop strategies and design of control electronics effect system performance. A ...

This talk, intended for the general chemical engineering audience, provides an overview and assessment of the research progress in the fields of dynamic operation of chemical processes and process ...
