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 ...

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 ...

Suppose you're called into the control room to correct an alleged loop tuning problem. Probably the worst thing you could do is to immediately begin changing a tuning parameter. There are several ...

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 ...

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 ...

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 ...

Except, that is, “when you consider the aging workforce and the institutional knowledge of processes and instrumentation that has been slipping away.” Thus, advances in ...

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 ...

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 ...
