You’ll learn about instrumentation and valves. The article identifies the importance of positioners in fast loops. How first-principle dynamic simulations provide insights into compressor surge, ...

In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Feb. 21, 2025 Control valve ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...

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 ...

In general, the best type of filter is a second order Butterworth, but a simple first order filter can do much to reduce controller output jitter and save the life of your valve or variable frequency ...

The new handheld control valve tester simplifies testing with dedicated tests that perform a quick health check to provide good/marginal/bad results Control valve testing has meant using complicated ...

Some wonder if AI will replace PID control loops. The reality is that, instead of replacing PID, AI is stepping in to help keep things running smoothly without upending regulatory trust. Think of AI ...
