Performance evaluation of an active and energy regenerative suspension using optimal control

Although the active suspension realizes a good performance of ride comfort, the energy consumption is a critical issue especially for electric vehicles. This paper proposed a novel concept of an active and energy regenerative suspension, and optimal control is applied. The performance of this suspension is compared with a passive suspension system and the energy regenerative potential is evaluated through a simulation of a quarter car model. Result shows that the active and energy regenerative suspension performs good ride comfort while have a good potential of energy regeneration.
