DeltaV community, I wanted to share a ControlGlobal.com article, Don't Over Look PID in APC by ModelingAndControl.com blog's Greg McMillan. He opens the article:

There is a confluence of capability and profitability for advanced control. Valves with smart digital positioners and new sensor technologies with smart transmitters have a resolution and threshold sensitivity better than 0.1%. Smart analyzers are more reliable and maintainable. An enhanced PID can deal inherently with analysis sample, cycle and multiplex time delays. A whole host of PID features available today can make optimization easier and faster to implement. At the same time, energy costs have more than doubled.

He shares ways to minimize energy use, maximize production, minimize reagents, minimize reactants, and maximize flexibility by applying different PID control strategies and using some of the inherent capabilities build into the DeltaV PID function block.

Have you applied PID control in any interesting ways that you can share?
