Power plants–especially coal-fired boilers–pose a set of process control problems unparalleled in other industries. Rapid load ramps, continuous unit demand changes, variable fuel quality and process ...

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 ...

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 ...

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 ...

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 ...
