A method of operating an active aerodynamic system of a motor vehicle includes detecting, via a system controller based on sensor data received from one or more sensing devices, a flutter excitation experienced by a spoiler of the active aero system during operation of the motor vehicle. The controller determines a harmonic oscillation amplitude of the flutter excitation experienced by the spoiler, and then determines if this harmonic oscillation amplitude exceeds a vehicle-calibrated threshold amplitude. If so, the system controller determines a damping force sufficient to mitigate or eliminate the harmonic oscillation amplitude.
