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 ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

Practical process control techniques including tuning single proportional integral derivative controllers, choosing appropriate control loops for a processing plant and measurement instrumentation. An ...

Author Dr. R. Russell Rhinehart discusses his new book, Nonlinear Model-Based Control: Using First-Principles Models in Process Control, and explains why nonlinear first-principles models should be ...

At the core of any modern industrial process is a control system guaranteeing precision, stability, and efficiency. Perhaps the most commonly used are PID (Proportional-Integral-Derivative) ...

In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...
