    Experimental Investigations of Generalizaed Predictive Control for Tiltrotor Stability Augmentation

    Experimental Investigations of Generalizaed Predictive Control for Tiltrotor Stability Augmentation


    A team of researchers from the Army Research Laboratory, NASA Langley Research Center (LaRC), and Bell Helicopter-Textron, Inc. have completed hover-cell and wind-tunnel testing of a 1/5-size aero elastically-scaled tilt rotor model using a new active control system for stability augmentation. The active system is based on a generalized predictive control (GPC) algorithm originally developed at NASA LaRC in 1997 for unknown disturbance rejection. Results of these investigations show that GPC combined with an active swash plate can significantly augment the damping and stability of tilt rotors in both hover and high-speed flight.
