摘要：
An earthmoving machine comprises a sensor, an implement, and control architecture comprising a controller and configured to facilitate movement in response to a signal indicative of a measured implement position and an implement control value comprising a gain value associated with implement speed. The controller is programmed to execute machine readable instructions to generate a surface-based cost function (SBCF) value based on the signal, determine whether the SBCF value is acceptable to lock the gain value, and generate a noise value that is based on an error between the signal and a target signal when the SBCF value is unacceptable, determine whether the noise value is acceptable to lock the gain value, adjust the gain value to control the implement speed when the noise value is unacceptable until the SBCF value or the noise value is acceptable, and operate the machine based on the locked gain value.
