When a PA is used without control, it is hard the meet the GSM specifications because the PA isn't accurate enough. Reasons for inaccuracy are: * The PA is a non-linear device * The PA is not stable ...

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 ...

For injection molding — as well as just about every plastic process — process cooling is very important for cycle time and part quality. Cooling sometimes seems like a last-horizon type of variable ...

Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...

Control loop performance-monitoring software can help to improve loop performance at electric power plants by automatically collecting data, assessing several aspects of loop performance, and ...

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

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 ...

Honeywell Industry Solutions announced recently that it has analyzed performance data from more than 100,000 control loops at 350 manufacturing facilities since the introduction of its Loop Scout ...

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 ...
