Hybrid Suspension System with Skyhook Control and Energy Regeneration (Development of Self-Powered Active Suspension)

Abstract

Abstract This paper presents a method of active vibration control system using regenerated vibration energy,i.e., the hybrid suspension system with active control and energy regeneration. In this system, all the energy for active control is supplied from a damper which regenerates vibration energy. In order to attain this system, less energy consumed control law and a device which can regenerate vibration energy are required. This paper proposes less energy consumed active control law using the concept of skyhook control. A linear DC motor which can convert kinetic energy to electric energy with high efficiency is developed as an actuator and an energy regenerative damper. From experiments and numerical simulations, it is proved that the proposed hybrid suspension system has better isolation performance than passive or semi-active suspension system without any energy consumption.
