The invention discloses a floating type wind energy and wave energy combined power generation device and a control method thereof, and belongs to the technical field of marine renewable energy utilization. The floating type wind energy and wave energy combined power generation device comprises a wind energy power generation module, a wave energy power generation module and a floating platform. Thewave energy power generation module is installed on the outer side of the floating platform through a plurality of hinge structures. A buoy of the wave energy power generation module drives a hydraulic cylinder to reciprocate and a hydraulic system to operate through a connecting arm under the action of waves, thereby driving a hydraulic motor and a hydraulic power generator to generate power. The control method of the hydraulic system includes the steps of detecting the motions of the platform in real time, and adjusting the flow of the hydraulic system through an adjustable throttle valve,thereby controlling the damping of the reciprocating motions of the hydraulic cylinder and effectively reducing the motion responses of a combined power generation platform. The floating type wind energy and wave energy combined power generation device can be completed on a same supporting structure, reduces the power generation cost and is a reliable marine renewable energy power generation platform. The control method of the hydraulic system is beneficial for improving the motion stability of the system.
