Regenerative control of active vibration damper and suspension systems

A new energy regenerative type vibration damper and suspension systems are introduced. It is intended for active damper to reduce energy consumption without losing damping efficiency. An electro-dynamic actuator is used for the regenerative damper. The electric energy is regenerated during the highspeed motion of the actuator. For lowspeed motion, active or passive control algorithm is applied to the same actuator to achieve a good damping performance. This idea is applied to a single degree-of-freedom vibrating system. The experimental results are showing that the system has better performance than the pure passive damper system and can regenerate vibration energy.
