Proportional-integral-derivative (PID) control is one of the most common types of automatic control used in the power industry. A PID controller continuously ...

ABB has introduced the Loop Tuning Accelerator Service, powered by ServicePort, to reduce the time between diagnosing control loop issues and tuning the loops to improve performance. ABB has ...

The tuning of proportional-integral-derivative (PID) control loops was an important change at HollyFrontier’s Navajo Refinery in Artesia, N.M. Its hands-on, “mandraulic” culture was no longer cutting ...

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 ...

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 ...

Optimizing power plant control systems can be challenging, but new tools are available to simplify and improve the process. On this episode of The POWER Podcast, Executive Editor Aaron Larson spoke ...

With the ever-increasing complexity of today’s printed circuit boards, the many voltages required to properly power all the integrated circuit loads are now managed by a range of point of load (POL) ...

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 ...

As digital transformation advances throughout manufacturing organizations, incorporating advanced process analytics ...

The importance of motor trajectory profiles and how they’re used in brushless DC (BLDC) motor control to minimize vibration and smooth out other performance issues. Why the PID loop is the most widely ...

A linear control variable yields a uniform surge margin across the full operating range and simplifies both closed-loop and ...
