Abstract
A control system is disclosed having at least one spray head, a fluid pump, and a power converter driving the fluid pump. The control system may also have an interface device to receive at least one parameter associated with a desired fluid delivery event, a pressure sensor configured to generate a first signal, a travel speed sensor configured to generate a second signal, and a controller. The controller may be configured to determine a desired fluid pressure based on the at least one parameter, and determine a control command for the power converter based on the desired fluid pressure. The controller may be further configured to determine a feedforward gain parameter based on the at least one parameter and the second signal, determine a feedback gain parameter based on a difference between desired and actual fluid pressures, and adjust the control command based on the feedforward and feedback gain parameters.
