Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...

Control valve selection plays a crucial role in optimizing control loop performance, and engineers must consider factors beyond just cost, leakage class and pressure drop. As explored in a Control ...

Loop-Pro Version 5 (v5) PID diagnostic and optimization software features non-steady state (NSS) modeling, which is said to improve control over complex production processes. According to the vendor, ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

Overlay control based on DI metrology of optical targets has been the primary basis for run-to-run process control for many years. In previous work we described a scenario where optical overlay ...
