Modeling and active vibration control of rigid-flexible coupled system on vehicle

When the missile is carried by vehicle, vibration caused by the road surface environment can lead to the missile fatigue damage. To investigate the active vibration isolation method of vehicle-mounted flexible missile system, a rigid-flexible coupled model is built. The vehicle and the flexible missile are respectively simplified as a quarter suspension system and a flexible beam fixed on a mass. A robust H_∞, controller is then designed for active vibration control. Simulation results verify that the proposed active vibration isolation method can reduce the vibration level more effectively compared with the passive isolation.
