摘要

An approach for designing an adaptive output feedback controller for uncertain systems with unmodeled dynamics and input uncertainty is developed. The adaptive control augments an assumed existing observer based linear controller. The main advantages of the method are that it can be used to augment an existing linear controller without modifying the parameters of that controller and it does not rely on the use of high gains neither in the observer nor in the the adaptation law. It is applicable to non-minimum phase systems and does not require realization of a reference model. Attitude control of a flexible spacecraft is used to illustrate effectiveness of the approach. Issues related to uncertainty in actuation effectiveness and sensor noise are also treated.
