Paper Title
On Control of Energy Flow in The Automotive Active Suspension System

Abstract
In the paper, energy recuperation and energy flow distribution in automotive suspension systems with linear electric motors controlled using a designed H∞ controller to obtain a variable mechanical force for a car active damper is presented. Vehicle suspensions in which forces are generated in response to feedback signals by active elements obviously offer increased design flexibility compared to the conventional suspensions using passive elements such as springs and dampers. The main advantage of the specified new solution using a linear AC motor is the possibility to generate desired forces acting between the unsprung and sprung masses of the car, providing good insulation of the car sprung mass from the road surface and load disturbances. In addition, under certain circumstances the application of linear motors as actuators enables to transform mechanical energy of the vertical car vibrations to electrical energy, accumulate it, and use it when needed. Energy flow control enables to reduce or even eliminate the demands concerning the external power source. Keywords - Automotive, Control, Linear Motor, Road, Suspension
