Abstract
A controller for an agricultural sprayer machine is configured to receive for each of a plurality of nozzle sets a respective upper pressure limit, a nozzle reference flow, and a nozzle reference pressure. For each one of the plurality of nozzle sets, a speed setpoint is calculated based upon the application rate setpoint, the nozzle reference flow, the nozzle reference pressure, and the product pressure setpoint.
Claims16
An agricultural sprayer machine, comprising:
- a fluid delivery network in selective hydraulic communication with a plurality of nozzle groups disposed in a mutually spaced relationship, wherein each nozzle group comprises a plurality of nozzles that can be independently activated, wherein, when activated, a nozzle of the plurality of nozzles is put into hydraulic communication with the fluid delivery network, wherein a nozzle set comprises at least one nozzle from each nozzle group;
- and
- an electronic controller configured to:
- receive an application rate setpoint and a product pressure setpoint;
- receive for each of a plurality of nozzle sets a respective upper pressure limit, a nozzle reference flow, and a nozzle reference pressure;
- calculate a speed setpoint for each one of the plurality of nozzle sets based upon the application rate setpoint, the nozzle reference flow, the nozzle reference pressure, and the product pressure setpoint;
- and
- control a forward speed of the agricultural sprayer machine based upon the speed setpoints.
