摘要：
This paper presents a two-degree-of-freedom (2DOF) controller, which is formed by combining a feedback (FB) controller with a feedforward (FF) controller, to control the vibration of the vehicle engine-body system, The robust feedback controller is designed by mu -synthesis to attenuate the effect of the engine vibration disturbance by modeling the vehicle engine-body system as a nominal 4DOF vibration system with parameter variations and unmodeled dynamics. Based on the filtered-x least mean square (LMS) algorithm, an active vibration controller is used as a feedforward controller to improve control performance further. Using an experimental device, which was designed to imitate the real vehicle engine-body system, some experiments have been made to demonstrate the effectiveness of the control scheme.
