The resources of the space orbit are limited. If the space debris is not cleaned up, after the number of the debris increases to a certain level, the collision between the existing debris will cause the speed of the debris to be greater than the speed of cleaning, thus causing "Kessler" effect, the space will no longer be available for use

The invention discloses an active-passive mixed control method for space object collision impact. The method aims at the problem of space object collision impact, and adopts a hybrid control method combining bionic structure controlled and active control methods to control the disturbance of the impact impact on the base; Firstly, the passive control method is adopted to dampen the impact through the deformation of the damping mechanism and nonlinear damping; secondly, the active control method is used to eliminate the external disturbance after mitigation. The invention combines the non-linear damping of the bionic structure to suppress the impact of the collision impact on the base of the spacecraft, and then eliminates the disturbance of the impact impact on the base through active control.
Description
technical field [0001] The invention belongs to the field of space target control, and in particular relates to an active and passive hybrid control method for space target collision impact. Background technique [0002] With the increase of space development and utilization activities, the number of space debris has increased dramatically. The resources of the space orbit are limited. If the space debris is not cleaned up, after the number of the debris increases to a certain level, the collision between the existing debris will cause the speed of the debris to be greater than the speed of cleaning, thus causing "Kessler" effect, the space will no longer be available for use. Therefore, the cleanup of space debris is an urgent task. Due to the rotation characteristics of a large number of space debris, collisions and impacts will inevitably occur. Therefore, it is necessary to propose an efficient and feasible solution to the problem of vibration and shock control of spa...
