针对挠性航天器在轨运动过程中挠性结构的持续振动问题，提出一种基于模糊控制原理的改进型自抗扰控制方法，实现对挠性航天器的振动抑制。通过非线性自抗扰控制器快速地抑制挠性航天器的低频振动，并结合模糊控制实现自抗扰控制器（Auto Disturbance Rejection Controller，ADRC）参数的自整定，提高自抗扰控制器的性能。将仿真结果与 PD 控制和非线性自抗扰控制进行对比，结果表明该控制算法能更加快速有效地抑制挠性航天器的振动，具有重要的理论研究和工程应用价值。

Considering the lasting vibration of flexible structure in the on-orbit motion process of flexible spacecraft, an auto disturbance rejection control(ADRC)strategy based on fuzzy control theory was proposed,so as to realize the vibration suppression of the flexible spacecraft.The nonlinear auto disturbance rejection controller was designed to quickly suppress the low frequency vibration in the flexible spacecraft.In order to improve the performance of ADRC,fuzzy control was also adopted to adjust the ADRC parameters easily.The simulation results of the PID control and the nonlinear ADRC control were compared and it is concluded that the controller can suppress the vibration of flexible spacecraft more quickly and efficiently.The results are of important value for further theoretical research and other engineering applications.
