            Abstract : 
A robust control method is proposed for quadrotor systems. The designed controller is developed based upon the quaternion representation model, which is subject to multiple uncertainties. A feedback controller is proposed to restrain the effects of nonlinearities and uncertainties on the closed-loop system. These uncertainties are considered as input equivalent disturbances and their effects are proven to be attenuated. Experimental results show the effectiveness of the designed control method.
