The basic characteristics of servo inertia generator and its application in helicopter vibration control are studied. First of all, a mathematical model of servo inertial force generator composed of electro-hydraulic servo controller, electro-hydraulic servo valve, hydraulic actuator, elastic element and inertial element is established. Then, the criteria for designing electro-hydraulic servo controller are established, The characteristics of the servo inertial force generator are analyzed. Then the design of the vibration controller based on the adaptive feedforward control is studied. Finally, the servo inertial force generator and the vibration controller are applied to the helicopter vibration control. Simulation shows that the servo inertial force generator can provide good damping effect.
