In this paper active suspension with linear electric motor has been designed. The active suspension is often hardly rejected for its big energy consumption. This contribution deals with direct real-time energy control in suspension system. The linear electric motor is used as an actuator. This motor can in specific situation generate the energy for next use. The H-infinity controller has been developed to improve car behavior, in particular passenger comfort and car stability. The second objective of the controller is to control energy distribution. Our submission is mainly focused on vehicle suspension, but it can be generalized to any kind of active suspension.
