To deal with the model uncertainties and external disturbances in quadrotor flying process, a novel sliding mode control based on extended state observer is proposed. System uncertainties are depressed and trace tracking errors are uniformly ultimately bounded under the proposed control law. Firstly, system model is divided into two subsystem models according to the coupling relationship between state variables. Extended state observers are designed to estimate mismatched uncertainties in the subsystem, and estimated values are added into switching function. Disturbances in the reconstructed system are observed by extended state observers designed based on the switching function, and they are rejected in the controller design procedure. Finally, system stability is proven through Lyapunov theory. The simulation results demonstrate the efficiency of the proposed control scheme for quadrotor trace tracking and the efficiency for depressing chattering phenomenon. Key words: quadrotor aircraft; trace tracking control; mismatched uncertainties; extended state observer; switching function; sliding mode control 1 (Introduction),.,.,,.,.,.
