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.
