The invention discloses a composite anti-rotation offset method for a wireless electric energy transmission system of an underwater vehicle. The composite anti-rotation offset method comprises an anti-rotation offset coupling mechanism for the underwater vehicle and an anti-rotation offset power stability control strategy. The anti-rotation offset coupling mechanism comprises two transmitting coil groups and a receiving coil group, the receiving coil group is of an annular structure and is formed by connecting six segmented coils in series, the winding directions of the adjacent coils are opposite, the first transmitting coil group and the second transmitting coil group are respectively formed by two coils which are connected in series, and the winding directions of the two transmitting coils in the same group are the same; according to the anti-rotation offset power stable control strategy, output power stable control is achieved by collecting the output power in real time, calculating the change rate of the output power and adjusting the phase angles of the two inverters, the first inverter drives the first transmitting coil set, and the second inverter drives the second transmitting coil set. According to the invention, the rotation offset tolerance of the system is improved, and stable transmission of output power under different rotation offset angles is realized.
