Paper Abstract

Precision Aerospace structures must be actively controlled to achieve stringent operating specifications; however, persistent disturbances will drastically reduce the benefits of active structure control unless the controller can be designed to counteract such disturbances. We present a scheme for reduced-order model based disturbance accommodating controllers for precision structures using the idea of a disturbance generator from Johnson. We show that closed-loop stability can be achieved using a compensation technique known as the residual mode filter from Balas3 for spillover-induced instabilities due to model reduction.
