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 ...

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

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 ...

Today's microcontroller units (MCUs) can implement the control functions and feedback loops of off-line ac-dc power converters, which do not require extremely fast control loops. As an example, a ...

The days when converter manufacturers would have little option but to rely on the expertise of power-module specialists to design filters, optimize the control loop, and provide the result, have given ...

It would be a masterpiece of understatement to suggest that control loop compensation holds much significance in power converter design. This is true in part because of increasing demand for ...

Application flexibility and cost concerns are creating a demand for intelligent power-supply designs that support soft configuration in production and external control. These advanced power supplies ...
