An indirect adaptive control using eigenstructure assignment

Advanced aircraft such as a control configured vehicle (CCV) provide the capability to control the aircraft in unconventional ways. One such approach is to generate decoupled motions, which can be used to improve tracking and accuracy by using eigenstructure assignment. However, generally, the robustness of eigenstructure assignment is not satisfactory under parameter uncertainty. In order to keep the high performance requirements under the undesirable situations, an indirect adaptive control using eigenstructure assignment is proposed. An example of a simple model is presented to illustrate the usefulness of the proposed algorithm and confirms the possibility of extension into flight control problems.
