Claim 10:
11. A method for controlling harvesting implement height of an agricultural harvester, the agricultural harvester including first and second actuators configured to adjust first and second operating parameters associated with a height of the harvesting implement relative to a field surface, respectively, the method comprising:
monitoring, with a computing system, the height of the harvesting implement relative to the field surface;
determining, with the computing system, an implement height error signal by comparing the monitored height of the harvesting implement to a predetermined target height;
dividing, with the computing system, the implement height error signal into a first frequency portion and a second frequency portion, the second frequency portion having a greater frequency than the first frequency portion;
controlling, with the computing system, an operation of the first actuator based on the first frequency portion of the implement height error signal; and
controlling, with the computing system, an operation of the second actuator based on the second frequency portion of the implement height error signal.
