Redundant command generator tracker control technique for self-repairing flight control systems

The command generator tracker (CGT) technique is used to design an explicit model following scheme in which the stabilizing feedback control law is designed to be a redundant control law. The scheme is applicable to the selfrepairing flight control system concept. The A-7D DIGITAC aircraft linearized data, at one flight condition and one type of impairment, is employed to demonstrate the validity of the approach. The employment of a redundant control law will increase the survivability and operational reliability of the aircraft and will enhance its maintainability during the combat and peace time missions.
