N2 - Focusing on the abrupt parameter variation of the aircraft dynamic characteristics brought by the wing damage, an observer based multivariable reference adaptive control(O-MRAC) method is presented. Firstly, The Multivariable Model Reference Adaptive Control (M-MRAC) method is studied to compensate the abrupt variations in the state matrix, control matrix and the constant uncertainty. In order to improve the tracking speed and precision, the Compensation Observer Unit(COU) based on Extended State Observer(ESO) is introduced and combined with the M-MRAC. Finally NASA Generic Transport Model (GTM) is taken as an example and several cases about different damage occasions are taken into consideration. Three-channel attitude simulations are presented and the results illustrate that the impact due to the parameter variations is significantly reduced, and the outputs tracks the desired trajectories rapidly and stably under uncertain damage.
