良好的空间微重力环境是开展各类空间科学实验的重要保证,然而由于各种扰动的存在,空间站内部微重力水平并不理想.基于此,本文在对微重力主动隔振系统的结构、动力学模型及控制目标进行理论分析的基础上,引入自抗扰控制方法,通过设计加速度控制回路、位置控制回路以及模型信息补偿,实现了系统位置控制和隔振控制的双重控制目标.最后,通过数字仿真对比,验证了本文所提出的控制方案具有优越的控制性能. The good space micro-gravity environment is an important guarantee for carrying out various kinds of space science experiments, however, due to various disturbances, the micro-gravity level in the space station is not ideal.On the basis of this, this paper analyzes the structure and dynamics of the micro-gravity active vibration isolation system Based on the theoretical analysis of the learning model and the control target, the self-disturbance rejection control method is introduced to achieve the dual control objectives of system position control and vibration isolation control by designing the acceleration control loop, position control loop and model information compensation.Finally, Compared with the digital simulation, it is verified that the control scheme proposed in this paper has superior control performance.
