In process flow control, there are many factors affecting variability, but the greatest contributor is the control valve’s performance. Issues associated with control valves, such as dead band, ...

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 ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

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

At the core of any modern industrial process is a control system guaranteeing precision, stability, and efficiency. Perhaps the most commonly used are PID (Proportional-Integral-Derivative) ...

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 ...

Although digital control systems—distributed control systems, programmable logic controller, and other automation equipment—are present in practically every process safety management (PSM) facility ...

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 ...
