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 ...

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 ...

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 ...

Can we improve performance by adding control elements external to the PID loop? Yes. Here we consider torque control and the related subject of torque feedforward — which can make systems run more ...

Some wonder if AI will replace PID control loops. The reality is that, instead of replacing PID, AI is stepping in to help keep things running smoothly without upending regulatory trust. Think of AI ...

“Ease-of-use might seem to be a boring [technology] quality,” observes Dennis Nash, chief executive officer and president of Control Station Inc. (www.controlstation.com), Tolland, Conn. Except, that ...

The NPS3000 series closed loop digital controllers are the Next Generation of NanoPositioning systems from SDL Queensgate. Designed specifically to control Queensgate's nanometer precision ...
