Abstract
A control system for assisting in applying a uniform layer of liquid to a substrate. The control system monitors a fluid pump advantageously integrated directly with an extrusion head. The pump receives the material to be deposited from a remote reservoir and controls dispersion of fluid to the extrusion head. The pump dispense rate is controlled by hydraulic pressure selectively applied by a flow control motor. The control system ensures that a steady-state flow of the liquid is maintained while preventing transient perturbations during initial extrusion startup.
