The invention discloses a six-degree-of-freedom magnetic levitation platform device which comprises a supporting frame, a moving frame and a magnetic levitation driving mechanism, the supporting frame comprises a first supporting frame, a second supporting frame and a third supporting frame, and the magnetic levitation driving mechanism comprises a first driving unit, a second driving unit and a third driving unit. Each driving unit comprises a stator fixed to the corresponding supporting frame and a rotor matched with the stator. The invention further discloses a control method of the magnetic levitation platform. By means of the first driving unit, the second driving unit and the third driving unit which are arranged respectively, the energization of the driving units or the direction, amplitude and phase of driving current of coils in the driving units are selectively controlled, the translation and rotation of the moving frame can be achieved, namely, six-degree-of-freedom movement is provided, and compar
