Uncertainity Estimation Based Approach To Attitude Control of Fixed Wing UAV

The backstepping(BS) algorithm as a promising advanced control law has been combined with the inertial delay controller(IDC) for the first time to handle time varying uncertainties and disturbances for fixed wing unmanned aerial vehicles. Other typical methods like sliding mode controller may need a relatively complex approach to handle uncertainties or under certain conditions may need a complete knowledge of the uncertainty bounds. The stability of overall system of backstepping and inertial delay controller for attitude control is proved and schemes are validated in simulations.
