On the Adaptive Control of Missile Autopilots

This paper deals with an adaptive control application involving a skid-to-turn missile. More particularly the yaw channel is adaptively controlled using two adaptive control algorithms derived with the shift operator and delta operator respectively. The latter is mainly motivated by its underlying numerical robustness which has been emphasized in Middleton and Goodwin (1987). In each case the time domain performances as well as the stability margins are shown to demonstrate the adaptive control performances vis à vis of that of the fixed parameter control.
