1 - Is PID control used in Feed Forward or Feed Backcontrol?
2 - We have a controller, and every time the Operator changesthe Set Point, the controller responds, and gets the process sortedout. Now, somewhere, we have read that load disturbances needed tobe considered in processes, as well. How will this controllerreact, if there is a load disturbance, and not a Set Pointchange?
