PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Some operators think so, observes Terry Blevins, principal technologist with Austin, Texas-headquartered Emerson Process Management’s (www.emersonprocess.com) DeltaV Product Engineering group.

The importance of motor trajectory profiles and how they’re used in brushless DC (BLDC) motor control to minimize vibration and smooth out other performance issues. Why the PID loop is the most widely ...
