The complex dynamics characters of mechanical centrifugal flywheel governor system are studied. The dynamical equation and the state equation of mechanical centrifugal flywheel governor system are established according to Lagrangian equations. By the phase portrait and Poincar6 map, the chaos forming process of the system is studied under the presented system parameters. The chaos controlling methods by the addition of constant motor torque, the addition of periodic force and the addition of phase are dissertated and analyzed numerically by the numerical solution. The chaos of the system is controlled by the three methods. The allowable range controlling variables and the steady orbit of the system under controlling are obtained.
