The invention provides an active-passive combined control system of a floating type offshore wind power structure and an implementation method. The system comprises a floating type foundation and a wind power generator arranged above the floating type foundation, an active control system which is at least composed of a wind speed measuring device, a wind power generator yaw device, a wind power generator variable pitch controller and a wind power generator variable pitch control terminal is arranged on the wind power generator, and a tuned mass damper providing passive control for vibration is arranged on the wind power generator; the wind power generator is provided with an inertial measurement unit sensor which is used for measuring three-axis acceleration and angular velocity at a cabin and a floating foundation motion control terminal which is used for receiving a velocity signal, and a plurality of telescopic full-revolving propellers controlled by the floating foundation motion control terminal are arranged on the floating foundation. According to the control system provided by the invention, real-time synchronous control of each substructure can be realized, average rotation and average horizontal displacement in structure movement can be counteracted through feedforward control, and the wind power generator can be effectively kept in a designed position to perform periodic movement.
