Starting from 1950, greater interest has been gained on active suspensions with respect to semi-active and passive systems. In a vehicle, the suspension system aims at satisfying the contrasting requirements of both comfort and handling, by insulating passengers from vehicle vibrations and providing constant tyre-road contact, respectively. One of the main advantages of active suspension is to provide the possibility of managing the trade off between vertical acceleration reduction and suspension travel usage through the choice of a suitable control strategy. The aim of this work is to set up a basic control model of an automotive active pneumatic system, to meet the essential performances of control and comfort.
