A multi-degree-of-freedom active damping mechanism control method, system and a damping mechanism are provided. A skyhook active damping control algorithm is used for controlling an electric cylinder output force in a vertical damping direction, and an adaptive control algorithm with an adaptive rate is used for correcting a load moment of inertia in pitch and roll damping directions. At the same time, a predictive model is established according to a task space linearization equation near an equilibrium point, and states of the system at N future moments are predicted in advance at each moment to achieve optimal control under complex constraints and reduce the influence of system delay. At the same time, the three control methods may further improve the active damping effect of the damping device by combining road information obtained by a visual sensor in real time.
