HP Control: Distillation column dual-temperature control—Part 2
Part 1 of this editorial1 has considered a distillation dual temperature control structure and concluded that such strategy is problematic and not likely to work. If you accept that dual-temperature c..
Improving data reconciliation and yield accounting
Here's how the Mathura Refinery's data reconciliation and yield accounting project was implemented
Fieldbus diagnostics: latest advancements optimize plant asset management
New field diagnostic profiles will benefit a wide range of automation stakeholders
HP Control: Distillation column dual-temperature control-Part 1
This editorial takes issue with a claim by Mr. Greg Shinskey that distillation dual-composition control cannot be done effectively by a multivariable predictive controller (MPC), but can be done effec..
Delayed coker heater analysis using an artificial neural network
The model was used to study the effects of the many variables that affect coke formation
Implement a constrained optimal control in a conventional level controller - Part 2
Novel tuning method enables a conventional PI controller to explicitly handle the three important operational constraints of a liquid level loop in an optimal manner as well as copes with a broad range of level control from tight to averaging control
HP Control: Back to the future: Process control in 2010
Where will process control money be spent in 2010? The choices include field instruments, safety systems (SISs), control system upgrades (DCSs), multivariable predictive control (MPC) and decision-sup..
HP Integration Strategies: Control in the field enables high-availability control
Replacing analog 4-20 mA technology with a digital network was a major driver behind developing FOUNDATION fieldbus technology. However, what really differentiates FOUNDATION fieldbus from Profibus PA..
