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 ...

The two most common categories of process responses in industrial manufacturing processes are self-regulating and integrating. A self-regulating process response to a step input change is ...

Half of all PID control loops will suffer performance degradation within their first year. So whether it's a loop in a motion drive or a refinery application, new intelligent tools can help ...

The International Society of Automation (ISA) announces that the newly released third edition of its Tuning of Industrial Control Systems book simplifies modern control system tuning by eliminating ...

Boilers have enormous thermal mass and are relatively slow to react. Turbines are nimble and quickly answer an operator’s command. Coordinating an entire plant requires an intimate knowledge of both ...
