Active control for a flexible aircraft wing in the presence of external disturbances

This paper investigates the problem of vibration reduction for a flexible aircraft wing with store. Active boundary control is developed to reduce the bending and twisting deflections of a flexible aircraft wing subjected to external disturbances. To handle the impact of the external disturbance, two extended state observers are designed under the active disturbance rejection control (ADRC) method. The developed control strategy guarantee the practical stability of flexible aircraft wing.
