US Patent 11785872 Closed-loop actively damped position control of an implement stabilizer wheel

A stabilizer wheel arrangement is actively damped when remotely positioning a stabilizer wheel of a towable agricultural implement by detecting an onset of ground-induced vibration and automatically introducing a phase-shifted vibration-countering or cancelling/damping modulation pattern into a signal that simultaneously and cooperatively controls the flow of hydraulic fluid to and from both the rod and base ends of the bore of a double-acting hydraulic cylinder, to hold the piston of the hydraulic cylinder at a target position determined from a desired position input signal corresponding to a desired position of the stabilizer wheel with respect to a frame of the agricultural implement.
