AN INVESTIGATION OF A SAMPLED-DATA SELF-ADAPTIVE FLIGHT CONTROL SYSTEM,
AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OHIO
A flight control system will adapt to changing dynamic pressure if the bandwidth of the air craft and controller is maintained several times that of an optimum series model. The Bendix System studied achieves the required bandwidth by the use of a variable-gain device that remains proportional to the inverse of airframe gain. Measured and predicted error signals are sampled to provide digital information to the variable gain circuit. Author
