Control loops incorporating proportional, integral, and differential (P, I, and D) factors have become standard functions of motion controllers. Many of the latest controllers also offer feed-forward ...

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 ...

Proportional, integral, derivative (PID) position servo-loop tuning can be daunting. However, one simple technique works well for most systems. Chuck Lewin • Founder and CEO | Performance Motion ...

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 ...

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 ...

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 ...

Let's presume that we have selected the valves and the transducers and even installed a controller. We now need to determine the controller settings - a practice that ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

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) ...

Click here for larger image. Thegraph in Figure 1 shows how the Levenberg-Marquardt algorithm enables findingthe system model even when the feedback data is noisy or the system has lowresolution ...

The Service is delivered through the company's ServicePort, a secure, remote-enabled service delivery platform deployed at customer sites. It uses data already gathered, analyzed and stored in the ...
