What is Process Manufacturing?

Process manufacturing refers to the continuous flow or batch production of something, often using automation, controls and instrumentation to improve quality, throughput and safety. Examples of process industries include refining, chemical, petrochemicsal, pulp and paper, electric utilities and wastewater, and many metals production methods.

The PID learning process

While there are many excellent loop tuning methods available, many practitioners prefer tweaking proportional-integral-derivative (PID) tuning constants or using rules-of-thumb rather than doing the required step test and data analysis. But having knowledge about how the individual PID components interact can go a long way to learning proper tuning theory and methods.
