Active vibration damping of mobile working machine involves smoothing load sensor output signal in low pass filter whose output is fed to position regulator as actual position value

摘要

The method involves controlling the pressure in a hydraulic cylinder (13) so that the actual load value detected by a load sensor (30) equals a defined desired value and regulating the position of the lifting unit by additionally influencing the cylinder pressure. The load sensor output signal is smoothed by a low pass filter whose output signal is fed to the position regulation arrangement as the actual position value.
