Abstract
This paper presents an innovative electronically controlled suspension system installed on a real car and used as a test bench. The proposed setup relies on a sensor network that acquires a large real-time dataset collecting the car vibrations and the car trim and, through a new controller based on a recently proposed theory developed by the authors, makes use of adjustable semi-active magneto-rheological dampers. A BMW series 1 is equipped with such an integrated sensors-controller-actuators device and an extensive test campaign, in real driving conditions, is carried out to evaluate its performance. Thanks to its strategy, the new plant enhances, at once, both comfort and drivability of the car, as field experiments show. A benchmark analysis is performed, comparing the performance of the new control system with the ones of traditional semi-active suspensions, such as skyhook devices: the comparison shows very good results for the proposed solution.

The sensor setup and the variational feedback control (VFC) controller described in the previous section and outlined in Figure 4 are mounted on board the real car, a BMW Series 1 E87, a test car that belongs to Sapienza
Summary
The proposed VFC is developed on an experimental platform which is based on Arduino with. VFC sensors is developed an experimental platform which is based on Arduino with interfaced commercial and isonemployed to control magneto-rheological suspensions. The second reason is to the source and inexpensive platform to test different control strategies. First architecture tested consists of four different of sensors, different types sensors, i.e.The accelerometers, gyroscopes, magnetometers, andtypes potentiometers, i.e., accelerometers, gyroscopes, magnetometers, potentiometers, an ethernet linked by an ethernet network employed to and connect them to a linked centralbycontrol unit. An internet protocol (IP) address is assigned to each unit, which is able to protocol (IP) address is assigned to platforms each unit, which is ableyet to communicate communicate with other control in a simple, robust, way. With other control platforms in a simple, yet robust, way Concerning this architecture, with reference to Figure Error!
