Abstract
Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmatched disturbance. Classical MRAC and σ-modified MRAC are the targeted controllers. Matlab/Simulink is used to simulate the wing rock phenomenon and to test the designed controllers. The simulated results show that the modified controller gives more robust characteristics than its counterpart; as it could confine different aircraft responses within bounded limits. Moreover, the modified controller shows lower control effort than classical one.
