Abstract
A controller for a peristaltic pump receives as an input pressure P.sub.i sensed at the inlet of the pump. The controller derives a nonlinear scale factor S.sub.Pi that varies as a step function with P.sub.i. The scale factor S.sub.Pi equals a first nonvariable value when P.sub.i lays in a first defined zone of inlet pressures, and equals a second nonvariable value, different than the first nonvariable value, when P.sub.i lays in a second defined zone of inlet pressures different than the first defined zone of inlet pressures. The controller generates a pump speed command based, at least in part, upon S.sub.Pi.
