面向引力波探测航天器多物理场噪声抑制的组件布局优化
Component layout design optimization for multi-physical field noise suppression in gravitational wave detection spacecraft
摘要
Abstract
The space-based gravitational wave detection mission places extremely high demands on the cleanliness of the core environment within spacecraft.To meet these demands,a Bilevel Sequential Optimization Approach(BSOA)is proposed to solve the Spacecraft Component Layout Design(SCLD)problem,aiming to effectively sup-press electromagnetic forces and self-gravity noise.SCLD is a typical mixed-integer programming problem,and the BSOA method is further formulated as a bilevel optimization problem for solution.The upper-level optimization is de-fined as an integer nonlinear programming problem to determine the orientation and region of components,while the lower-level optimization is defined as a real-valued nonlinear programming problem to optimize the placement of com-ponents within the selected region.By introducing a feedback iterative mechanism,the results of the lower-level opti-mization influence upper-level decisions,enabling progressive optimization of the layout scheme.Within the bilevel se-quential optimization framework,an elite genetic algorithm is employed for global optimization of the upper-level prob-lem using,while the lower-level problem is locally searched using a differential evolution algorithm.To address various technical challenges in the optimization process,a hybrid encoding strategy is proposed to meet the coding require-ments of evolutionary algorithms,a regional division strategy is introduced to discretize installation positions,and a col-lision detection approach is implemented to identify violations of geometric constraints among components.Experimen-tal results demonstrate that the proposed approach efficiently solves layout design problems under complex multi-constraint conditions,generates layout schemes that meet scientific mission requirements,and significantly outper-forms traditional single-stage and two-stage optimization methods in terms of performance indicators such as mean and standard deviation.This approach exhibits significant application potential and extensibility,laying a technical foundation for future gravitational wave detection missions.关键词
