Abstract: A control system includes a first input to receive a positional output characteristic of a first vehicle at a first communication frequency and a second input to receive a kinematic output characteristic of the first vehicle at a second frequency, where the second frequency is greater than the first frequency. A guidance controller of a second vehicle is configured to process the kinematic output characteristic of the first vehicle to obtain a heading of the first vehicle, compare the heading of the first vehicle with a heading of the second vehicle to obtain a heading deviation of the second vehicle, and determine a guidance heading of the second vehicle based on the heading deviation of the second vehicle. A control interface is configured to communicate the guidance heading to one or more of steering, throttle or brake elements of the second vehicle.

Abstract: A sprayer control system includes a plurality of smart nozzles each having at least one control valve with a valve operator, an electronic control unit for the valve operator, and one or more spray nozzles. The at least one control valve and the ECU control a flow rate of liquid agricultural product through the nozzles. A duty cycle modulator is in communication with the ECU and generates an applied duty cycle for the at least one control valve. The duty cycle modulator includes a specified duty cycle input having a specified duty cycle and a pressure monitor associated with the at least one control valve. A pressure comparator compares the valve pressure determined with the pressure monitor with a system pressure and generates a pressure error. An applied duty cycle generator generates the applied duty cycle based on the specified duty cycle modified by the pressure error.
