摘要
卫星在轨运行时,会因为燃料的减少,助推装置气体的排出使自己质心位置发生变化.针对这种情况,根据工业常用的丝杠导轨,设计了一种质心调节的方法及组件.为了使导轨能精准的定位,采用了萤火虫算法对控制丝杠导轨定位的PID参数进行寻优,进行Matlab仿真验证.并实际测量了质心调节组件的定位精度.
Abstract
When the satellite is in orbit,the position of its center of mass will change due to the emission of booster gas due to the reduction of fuel.In view of this situation,according to the commonly used lead screw guide rail in industry,a method and com-ponent of mass center adjustment are designed.In order to locate the guide rail accurately,the firefly algorithm is used to optimize the PID parameters controlling the positioning of the lead screw guide rail,which is verified by Matlab simulation.The positioning accuracy of the centroid adjusting assembly is measured.
