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 ...

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 ...

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

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 ...

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 ...

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 ...

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 ...

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 ...

If the valve and sensor are properly sized and ranged, then most loops of a particular type will have similar tuning parameters. Thus, by using a table of typical values, one can start with tuning ...

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 ...
