A method of controlling an active aerodynamic element for a vehicle includes determining a target position for the active aerodynamic element from a target aerodynamic force, which may be a given value that is provided based on dynamic conditions of the vehicle. The method actuates the active aerodynamic element to the target position and senses an aerodynamic response characteristic of the active aerodynamic element while actuated to the target position. An estimated applied aerodynamic force is determined from the aerodynamic response characteristic, and is compared to the target aerodynamic force. A force error is determined from the comparison of the estimated applied aerodynamic force and the target aerodynamic force, and a modified position for the active aerodynamic element is determined from the force error and the target aerodynamic force. The active aerodynamic element is actuated to the modified position.
