Combined type self-powered active vibration control of truck cabins

A self-powered active suspension, which produces control force using energy regenerated by dampers, is applied to truck suspensions. Such systems do not require external energy to produce control force. To discuss its feasibility, the balance between the regenerated and the consumed energy is examined and active controllers that can achieve active control with regenerated energy are obtained. Control schemes for the self-powered system are presented, and their performances are examined through numerical simulations. The results show that the system achieves active vibration control without external energy, and has better suppression performance than passive or semi-active control systems.
