A method for calibrating a height control system for an implement of an agricultural work vehicle, the method comprising: providing, with one or more computing devices, an input signal to the height control system to adjust a height of the implement relative to the ground surface; monitoring, with the one or more computing devices, the height of the implement relative to the ground surface; and adjusting, with the one or more computing devices, at least one gain of the height control system; determining, with the one or more computing devices, a maximum stability gain of the height control system based on the at least one gain and the monitored height, 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, with the one or more computing devices, the at least one gain of the height control system based on the maximum stability gain; wherein providing the input signal to the height control system comprises iteratively providing step input signals to the height control system; adjusting the at least one gain of the height control system comprises iteratively increasing the at least one gain of the height control system concurrently with providing the step input signals to the height control system; 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; and determining the maximum stability gain of the height control system based on the at least one gain comprises 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. providing, with one or more computing devices, an input signal to the height control system to adjust a height of the implement relative to the ground surface; monitoring, with the one or more computing devices, the height of the implement relative to the ground surface; and adjusting, with the one or more computing devices, at least one gain of the height control system; determining, with the one or more computing devices, a maximum stability gain of the height control system based on the at least one gain and the monitored height, 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, with the one or more computing devices, the at least one gain of the height control system based on the maximum stability gain; wherein providing the input signal to the height control system comprises iteratively providing step input signals to the height control system; adjusting the at least one gain of the height control system comprises iteratively increasing the at least one gain of the height control system concurrently with providing the step input signals to the height control system; 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; and determining the maximum stability gain of the height control system based on the at least one gain comprises 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.
