For example, if a feedwater flow control loop oscillates because its set point is oscillating, the problem lies with the drum level controller. The fault analysis should then be applied to the ...

For example, if a pressure-reducing control loop is closely followed in the process by a flow control loop, the two control loops can appear to be fighting each other, causing both loops to oscillate.

That means the relationship between the controller output signal versus the control valve flow rate will be changing throughout all the different operational conditions and the loop tuning parameters ...

Discover how IoT technology is transforming smart water management. Learn how utilities optimize pressure control, reduce costs, and improve efficiency using solutions like Aquestia''s Hydraulic ...

A level controller cascades down to the setpoints of the two reagent flow control loops (A and B) via ratio stations. In the example, the reagent flows have target ratios of 68 percent for “A” and 32 ...

The research flow loop created by students at the Univeristy of Tulsa is used to study how a clean hole can be created during the drilling process. Major components include an 81 foot long transparent ...

To implement this control loop, Analog Devices announced the LTM4663, a complete 1.5-A sink/source thermoelectric cooler (TEC) regulator in a 3.5- × 4- × 1.3-mm LGA package (Fig. 1).
