Abstract

Systems and methods are provided for determining and controlling the location of an interface between separated blood components within a centrifuge. An optical monitoring assembly is used to determine the position of the interface, with the current position being compared to a target position. An error signal, which is indicative of the distance between the two positions, is input into a proportional-integral-derivative control algorithm to generate a control signal. The control signal is used to modify the rate at which a separated blood component is removed from the centrifuge so as to move the interface toward the target position. Blood characteristics, blood source characteristics, and/or the rate at which blood is pumped into the centrifuge are monitored for any changes, with a change in one or more of these factors being used to modify the control algorithm.
