The invention discloses a wave compensation anti-swing method for an active ship, which comprises the following steps: analyzing energy dissipation by adopting an automatic anti-swing control algorithm of an under-actuated system based on energy dissipation, distributing energy according to the actual working condition of the system, and controlling the energy dissipation by adopting a displacement sensor and a hydraulic compensation cylinder system. The method comprises the following steps: analyzing wave motion in combination with a wave motion short-time forecasting algorithm based on a time sequence, segmenting a track of the wave motion according to time, and predicting and analyzing an actual track of a system under a next step length through a controller under a set fixed step length; according to a signal acquisition method based on extended Kalman filtering, data are observed and collected through input and output of a system by using a linear system state equation; the wave compensation system is controlled through a wave compensation core intelligent control algorithm under time delay, the responsiveness of the system is improved through intelligent control, and delay faults of the system are reduced.
