Regenerative control of active vibration damper and suspension systems

Abstract

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 high-speed motion of the actuator. For low-speed motion, an 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 show that the system has better performance than the pure passive damper system and can regenerate vibration energy.
