Abstract: Considering the problem of acceleration tracking of gliding guided projectiles in the case of the uncertaint internal and external disturbances and the time delay of canard deflection command, a nonlinear active disturbance rejection acceleration tracking controller is designed based on the active disturbance rejection control technique. The controller is simple and easy to implement, and requires small amount of calculation and less parameters to be adjusted. The numerically simulated results show that the proposed active disturbance rejection controller can accurately control the output acceleration to track the acceleration command under the conditions of strong disturbance and delayed response of canard, and has better disturbance-resistant capability. Moreover, the canard deflection control command changes slowly from zero, which effectively reduces the control burden of canard system. In addition, the proposed controller has strong adaptability and robustness to the large-scale perturbation of the aerodynamic coefficients and the lag coefficient of canard. Key
