Abstract
In many years, active controls of automobile suspension were studied for improved ride comfort and compatibility between stability and isolation. However, active control uses so much energy that active suspension hasn't been put to practice use except for some luxury cars. Authors fundamentally study on energy saving control of automobile suspension using electromagnetic damper, which can convert vibration energy of vehicle to electric energy. In this paper, authors propose energy saving control of automobile suspension considering velocity feedback gain of not only sprung mass but also unsprung mass. Electromagnetic suspension system is modeled as quarter-car model, and then validated by experiments.
