摘　　要：针对旋转弹运动过程中的气动耦合、控制耦合等非线性问题,提出基于反步法的自适应滑模控制器设计方法,利用饱和函数代替符号函数削弱抖振现象,有效抑制了旋转弹气动参数摄动对控制品质的影响,增强控制系统的鲁棒性,实现对旋转弹的稳定控制。利用Lyapunov法验证了控制方法的稳定性,并通过仿真验证了所设计方法的有效性。A design method for an adaptive sliding mode controller based on the backstepping method is proposed to address the nonlinear issues of aerodynamic coupling and control coupling during the motion of a rotating projectile.The saturation function is used instead of the sign function to weaken the chattering phenomenon,effectively suppressing the influence of aerodynamic parameter perturbations on control quality,enhancing the robustness of the control system,and achieving stable control of the rotating projectile.The stability of the control method was verified using the Lyapunov method,and the effectiveness of the designed method was verified through simulation.
