:Modeling, Control and Automatic Calibration of a Semi-Active Suspension System for a SportscarAbstract:
The main objective consists in developing intelligent algorithms which can enhance the performance of
sportscars. This class of vehicles are equipped with cutting-edge technology, in terms of sensors and
actuators, which is not yet fully exploited in its potential and has considerable leeway for scientific
My research is focused on the suspension system which plays the main role in shaping the desired
vehicle dynamics, and it is responsible for the comfort and handling performance of the vehicle. A
professional driver is very sensitive to this system and it is therefore of utmost importance to have a
good understanding of its building blocks in order to deliver the best possible performance.
First, I ran testbench experiments on the Magneto-Rheological damper and developed a mathematical model which can describe its behavior. Then, I proposed a control logic which can achieve top performance in the control of the vertical dynamics of the vehicle. Finally, I investigated an automatic calibration framework based on Bayesian Optimization which can optimize the control parameters of the control logic.
