Claim 8:
9. A height control system for an implement of an agricultural work vehicle, the height control system comprising:
an implement;
an implement height sensor configured to detect a height of the implement relative to a ground surface;
an implement controller communicatively coupled to the implement height sensor, the implement controller including a processor and associated memory, the memory storing instructions that, when executed by the processor, configure the implement controller to perform operations including:
providing an input signal to the height control system to adjust the height of the implement relative to the ground surface, wherein providing the input signal to the height control system comprises iteratively providing step input signals to the height control system;
monitoring the height of the implement relative to the ground surface based on signals received from the implement height sensor;
adjusting at least one gain of the height control system by iteratively increasing the at least one gain of the height control system concurrently with providing the step input signals to the height control system, wherein iteratively increasing the at least one gain of the height control system concurrently with providing the step input signals to the height control system comprises increasing the at least one gain of the height control system until the at least one gain of the height control system is approximately equal to the maximum stability gain of the height control system;
determining a maximum stability gain of the height control system based on the at least one gain and the monitored height and storing, in a non-transitory computer-readable media, the at least one gain when the at least one gain is approximately equal to the maximum stability gain, Wherein the maximum stability gain corresponds with a stability point of the height control system at which the height control system transitions from stable to unstable; and
setting the at least one gain of the height control system based on the maximum stability gain.
