Process Control - an overview | ScienceDirect Topics
W. Brian Rowe, in Principles of Modern Grinding Technology, 2009. Intelligent Control. Intelligent control is where the CNC can change an input process control parameter it has been given to improve process operation. An example of intelligent control is where the feed position for final size is changed in response to a sensor measurement such as a diameter gauge.

Jul 15, 2021· Some processes, by nature, have some process time delay or deadtime. For example, a pH controller must have some deadtime, we must wait until the chemical neutralization finishes before measuring the pH. Deadtime is the mortal enemy of a PID controller; it is the most destabilizing process parameter.

Feb 04, 2021· The industrial production process of copper sulfate pentahydrate includes the following steps: (1) Grinding, where the size of the larger fragments of the ore is reduced to ¼ inch; (2) Acid Agglomeration, where the crushed ore is agglomerated with water and sulfuric acid concentrated (98%); (3) Heap leaching, where copper is obtained from,
6 Deformation Processes | Unit Manufacturing Processes,
This systems approach, as illustrated in Figure 6-1 and Table 6-1, allows the study of the input/output relationships and of the effects of process variables on product quality and process economics. The key to successful metal deformation (i.e., to obtaining the desired shape and properties) is the understanding and control of metal flow.
