| contents | The growing focus on reducing energy consumption, particularly in electric vehicles with limited autonomy, has prompted innovative solutions. In this context, we propose a real-time flap-based control system aimed at improving aerodynamic drag in real driving conditions. Employing a Recursive Subspace based Predictive Control (RSPC) approach, we conducted wind tunnel tests on a representative model vehicle at reduced scale equipped with flaps. Comprehensive assessments using pressure measurements and Particle Image Velocimetry (PIV) were undertaken to evaluate the control efficiency. Static and dynamic perturbation tests were conducted, revealing the system's effectiveness in both scenarios. The closed-loop controlled system demonstrated a substantial gain, achieving a 5\% base pressure recovery. |
