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 ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

Tuning a PID controller is pretty straightforward, once you know how to start and what steps to follow. In this series on motion control, we have already discussed permanent magnet brushed and ...

Creating a digital twin has become a major goal for digitalization, and it is easy to get intimidated by all the buzzwords. The digital twin concept is really about creating a macro control loop with ...

In my previous article on loop tuning, I discussed the importance of field data collection and the importance of a methodical approach to PID tuning. I introduced the concept of the bump test and how ...

Steve Sandler explains what every engineer should know about ‘non-invasive’ stability assessments. The non-invasive stability assessment is a method that uses an output impedance measurement to ...

Designing the compensation network in a DC/DC converter can be a mystery if one does not know where to place the poles and zeros of the error amplifier and how much ...
