Explain What Are De-saturators? |
|
Answer» When, in some processes, e.g. BATCH processes, long transient responses are expected during which a SUSTAINED deviation is present the controller integral ACTION continuously drives the output to a MINIMUM or maximum VALUE. This phenomenon is called ‘integral saturation of the control unit'. When this condition is met, then this unit is de-saturated.
