Interaction among and between zones makes the difficult job of controlling temperature still more challenging. The dynamic behavior can result in increased cycle times and even undermine material transformation. Knowing when dynamics change and how they affect production are keys to success.
Upsets are to be expected in most production environments but processes should be designed for an appropriate response. Advanced applications of the PID such as Cascade Control provide effective disturbance rejection, limiting the impact of everyday upsets.
Process performance typically degrades as changes in feedstock or other production inputs occur. The long Dead-Time associated with those processes can result in a protracted deviation from Set Point. Feed-Forward is an effective control strategy for curbing a negative process response and maintaining steady control.
