In the paper, energy recuperation and energy flow management in active automotive suspension systems with linear electric motors controlled using a proposed H-infinity controller to obtain a variable mechanical force for a car damper is presented. The main advantage of the proposed 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 disturbances. In addition, under certain circumstances using linear motors as actuators enables to transform mechanical energy of the vertical car vibrations to electrical energy, accumulate it, and use it when needed.
