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 ...

According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Feb. 21, 2025 Control valve ...

Pneumatic furnace damper drives may be more common, but electro-hydraulic actuators provide several advantages to the more traditional control scheme. One fossil-fired plant in Taiwan achieved more ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

PID (proportional, integral, derivative) control has existed for decades and there are many tools available to help implement PID to tune process control systems, thereby making it generally easy to ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

Feedback-control schemes for linear systems have been around since at least the 17 th century, regulating pressure and distance between millstones and then, famously, to control James Watt’s steam ...
