Abstract
A system for controlling harvesting implement height of an agricultural harvester may include a computing system configured to monitor the height of a harvesting implement of the harvester relative to a field surface based on the received sensor data. Additionally, the computing system may be configured to determine an implement height error signal by comparing the monitored height of the harvesting implement to a predetermined target height. Moreover, the computing system is configured to divide the determined implement height error signal into a first and second frequency portions, with the second frequency portion having a greater frequency than the first frequency portion. Furthermore, the computing system is configured to control the operation of first and second actuators of the harvester based on the first and second frequency portions of the implement height error signal, respectively.
