ABSTRACT:
A system and method are disclosed for determining process dead time and for controlling a process using a dead time compensated control loop. The dead time is determined from a cross-correlation function of a perturbing signal applied to a processing station and the output of a sensor which detects physical characteristics of the product controlled by the processing station affected by the perturbing signal.
