摘　　要：针对星座构形一体化设计时,由于约束条件复杂而导致求解困难的问题,提出了自适应序列约束边界法和约束邻域排斥策略,以进化算法为基础构成了星座构形一体化优化设计方法。应用此方法进行了全球导航星座构形一体化优化设计,设计结果表明该方法能够高效解决综合考虑多种设计因素、具有离散/连续混合变量、无导数信息的星座构形一体化优化设计问题。The optimization method to solve the problem of the integrated design optimization of constellation configuration was studied which is based on the evolution algorithm. To deal with the complex constraints, a set of effective constraint handling methods including adaptive sequence constraint boundary method and constraint neighbor region rejection strategy were put forward. This method was applied to a design mission of global navigation constellation. The design result demonstrates that the method is effective to the complex design optimization problem of satellite constellation configuration which needs to deal with many complex design factors, including continuous and discrete variables without gradient information.
