For the model uncertainty  the external disturbance and the coupling factor are considered  an active disturbance rejection control (ADRC) algorithm is introduced into the designing procedure. The aircraft dynamic model is proposed in this article  based on which the closed-loop control system is divided into four independent channels with the coupling factor compensated by the extended state observer (ESO). The nonlinear state error feedback (NLSEF) algorithm is designed in each channel to improve the closed-loop dynamics. In this article  the ADRC controller is expressed in the discrete form. And finally  the simulation results show that the proposed control algorithm achieves a favourable tracking performance. 2012 IEEE.
