Operator induced oscillation filter to prevent instability from operator

摘要

A system for controlling manual input device damping, and a related method and computer program product are disclosed. The system may comprise a manual input device mounted on a machine, a sensor that transmits to a controller an input signal indicative of the motion, acceleration, and/or deceleration of the machine, a variable damper that selectively alters the resistance of the input device to displacement based on a command signal transmitted by the controller, and a controller configured to adjust the resistance of the input device by adjusting the damping provided by the variable damper based on filtering of a historical trend of oscillation amplitudes at a frequency of concern.
