Nozzle control system and method

A sprayer control system configured to control spray characteristics of spray nozzles, the sprayer control system comprising:

• a master node configured for coupling with one or more of a system pressure valve or a system pump, the master node is configured to:
• control the system pressure of a liquid agricultural product, and
• determine an error correction, the error correction based on the difference between an actual system flow rate and a sum of target flow rates;
• and
• a plurality of smart nozzles, each of the smart nozzles includes at least one control valve and an electronic control unit (ECU) in communication with the master node, the at least one control valve and the ECU are configured to control a component flow rate of liquid agricultural product through one or more spray nozzles, each smart nozzle is configured to:
• determine the target flow rate for the one or more spray nozzles with the ECU,
• determine a duty cycle for the one or more spray nozzles with the ECU, the duty cycle based on the target flow rate and the error correction, and
• operate the at least one control valve to deliver the liquid agricultural product to the one or spray nozzles according to the duty cycle.
