== derivative term ==
"The derivative term is used to provide damping or shaping of the response". It is NOT the case
The derivative terms have a higher gain to fast changes in the difference signal, promoting a fast recovery of the system.
there is no damping effect of the derivative term, just the opposite. [[User:Cuye|Milton]] ([[User talk:Cuye|talk]]) 23:11, 25 August 2023 (UTC)
== Integral term ==
"The integral term permits the rejection of a step disturbance" is NOT true.
The integral term accumulates the error, so the output goes to the set point.
The step disturbance affects the derivative term. [[User:Cuye|Milton]] ([[User talk:Cuye|talk]]) 23:38, 25 August 2023 (UTC)
== Adding a more general figure of a control loop? ==
In my opinion, it could be helpful for overall understanding to add a general illustration of a control loop in addition to the chemical plant (see [https://upload.wikimedia.org/wikipedia/commons/d/d2/Closed_Control_Loop.svg this] figure). If there are no objections from the community, I would add this illustration (including the naming of the variables) to the main article.
