Process 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..
Implement a constrained optimal control in a conventional level controller - Part 1
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
Fine tune accuracy in analytic measurement - Part 3
Follow these steps to avoid compromising a sample
HP Control: More on APC designs for minimum maintenance
Perhaps Zak Friedman struck the perfect balance in his series of editorials,1 because while Dr. Latour thinks Zak went too far in his suggestions to prune multivariable control (MPC) matrices,2 I woul..
Fine tune accuracy in analytic measurement - Part 2
Follow these recommendations for correct analyzer calibration
HP Control: APC for min maintenance or max profit? - Part 2
While I have promoted proper control system performance indicators18–25 since 1964, like Dr. Y. Zak Friedman,1 I also am aware of some deeper problems with realizing its full commercial potential..
Practical process control system metrics
Here are several useful examples
Agile supply chain planning
Providing a common workspace improves data integration
Service-oriented architecture simplifies data source integration
