The high gain, wide bandwidth precision tracking/pointing systems used on advanced aircraft necessitate the consideration of aeroservoelasticity (ASE) early in the design process. Aircraft control systems are designed to meet stability, performance and, in the case of manned aircraft, handling qualities criteria defined by the Mil-Spec requirements. As digital controllers are introduced, airframes are made statically unstable, and as the push for increased dynamic response continues, the aeroservoelastic influences become increasingly important in the overall system performance. At times, the ASE considerations may dominate the rigid body control law design effort. This paper summarizes an approach to the ASE stabilization of a fighter aircraft when used as the integral part of a high bandwidth manual or automatic fire control tracking system. The same approach can be applied to standard manual control aircraft where a more thorough ASE analysis is desired.
