为了减少在库仑卫星编队运动过程中不确定因素的影响,避免控制过程中发生抖振现象,提高控制器的稳定性、准确性,设计了适用于二体旋转库仑卫星编队的反馈线性化滑模控制方法。首先在地月系平动点L_2点处附近建立二体旋转库仑卫星编队的动力学模型并进行简化,针对库仑编队动力学特性,在滑模控制中加入了线性化反馈项,保证了编队整体的鲁棒性;仿真结果证明,该方法能够使编队达到预期构型,具有良好的控制性能。
In order to reduce the influence of uncertain factors during the formations of Coulomb satellites, to avoid chattering in the control process and improve the stability and accuracy of the controller, a feedback linearized sliding mode Control Method. Firstly, the dynamics model of two-body rotating Coulomb satellites formation is established near the L_2 point of the translational moon system, and simplified. Based on the kinetic characteristics of Coulomb formation, a linearized feedback term is added to the sliding mode control to ensure the formation The simulation results show that this method can make the formations reach the expected configuration and has good control performance.
