| 摘 要： | 通信卫星在轨运行时,行波管放大器发生故障,如何准确快速切换到备份放大器是卫星运营商十分关注的问题。文章提出了一种基于遗传算法的星载功率放大器的备份环开关切换方案,通过编码将开关及其位置信息融入染色体中,根据设计的适应度值计算来判断染色体即开关切换方案的优劣,采用选择-交叉-变异的循环来模拟生物种群的繁殖、竞争、淘汰、平...

| Abstract: | How to accurately and quickly find the best redundancy switching solution of redundancy ring is an important concern for satellite service providers if a travelling wave tube amplifier(TWTA) fails in orbit.However,with the development of telecommunication satellites in the direction of large capacity and long endurance,redundancy ring is bigger and bigger,integrated redundancy rings appear,and redundancy switching solution becomes more and more complex.Traditional enumeration method is inefficient and unrel... |
