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 ...

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 ...

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 ...

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 ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...

In the electronic field, an oscillator is a circuit capable of producing a self-sustained sinusoidal signal. In a lot of configurations, cranking up the oscillator involves the noise level inherent to ...

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 ...
