Allowing readers to develop professional competencies, this text is aimed at engineers and technicians who need a practical understanding of the essentials of process control, loop tuning and how to ...

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.

to achieve a higher-level control objective. At the same time, the flow controller is a true mitigator of unmeasured disturbances. It is typically characterized as a high-frequency loop, meaning that ...

The previous sections of this chapter have dealt with the tuning of controllers for self-regulating processes such as temperature and flow. Liquid-level control, however, has characteristics ...
