Active Control for Power-train Vibration of Automotive Using Active Mounts
In this work,a new active mount featuring piezostack actuators and a rubber element is proposed and applied to a vibration control system.After describing the configuration and operating principle of the proposed mount,an appropriate rubber element and appropriate piezostacks are designed.Through the analysis of the property of the rubber and piezoelectric stack actuator,a mechanical model of the active vibration isolation system with the active mounts is established.An optimal control algorithm is presented for engine vibration isolation system.the controller is designed according to linear quadratic regulator (LQR) theory.Simulation shows the active system has a better consequence in reducing the vibration of the chassis significantly with respect to the ACM and the optimal control than that in the passive system.
