| Bibliography: | CHENG Chun-Hua HU Yun-An WU Jin-Hua（ 1. Department of Control Engineering, Naval Aeronautical and Astronautical University, Yantai 264001） In this paper, a novel control approach based on the combination of back-stepping design and auto disturbance rejection is presented for a class of non-affine nonlinear pure feedback systems with modeling uncertainties and external disturbances. During every step of back-stepping, the auto disturbance rejection control is adopted, meanwhile, a differentiator and an extended state observer （ESO） are respectively used to estimate the virtual control of the derivative and the unknown part of the system. It is different from other existing methods, which employed approximation theory to directly construct the controller for the non-affine nonlinear systems. The design procedure of this proposed scheme is not complicated, and the input to state stability （ISS） analysis shows that the system states can asymptotically converge to an arbitrarily small region of the equilibrium poin |
