Abstract
A direct adaptive controller was developed for a class of interceptors. The control design architecture is based on a model reference adaptive control concept. The adaptive control algorithm is configured together with a traditional attitude control system (ACS) to provide robust performance. System uncertainties arising from inertial measurement noise, center of gravity movement, mass property variations, and sensitivity to different engagement geometries were used to evaluate the performance of the combined adaptive-traditional ACS. A detailed description of the controller architecture and an evaluation of its performance subject variations in endgame geometry will be the main focus this paper.
