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 ...

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 ...

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 ...

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 ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...
