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 ...

Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...

Control loop performance-monitoring software can help to improve loop performance at electric power plants by automatically collecting data, assessing several aspects of loop performance, and ...

As an executive in the business process outsourcing (BPO) industry, I have seen firsthand how outsourcing has helped businesses to scale up and operate more efficiently. However, with the advancements ...

Driving a light-emitting diode (LED) or LED array is not without its challenges. The LEDs require a well-designed constant-current source for controlled brightness. More specifically, the output ...

Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...

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 ...

For injection molding — as well as just about every plastic process — process cooling is very important for cycle time and part quality. Cooling sometimes seems like a last-horizon type of variable ...
