1. A sprayer control system, comprising:
a smart nozzle, comprising:
a control valve;
at least one nozzle in communication with the control valve, the nozzle configured to apply an agricultural product; and
an ECU in communication with the control valve and configured to operate the control valve, the ECU including:
a system interface configured to receive a target system flow rate and an error between the target system flow rate and an actual system flow rate, wherein the system interface is configured to receive one or more of speed of a boom, yaw rate of the boom, width of the boom, or location of the nozzle along the boom; and
the ECU is configured to generate a nozzle flow rate based on the target system flow rate, the error, and one or more of the speed of the boom, the yaw rate of the boom, the width of the boom, or location of the nozzle along the boom, and implement the nozzle flow rate at the control valve.
