摘要
在利用遗传算法的系统参数辨识中 ,利用了灰色理论中的趋势关联分析方法来构造遗传算法的适值函数 ,在适值函数的选择上兼顾了“接近性”和“相似性”的要求 ,仿真结果证明 ,本方法克服了常规遗传算法容易早熟的缺点 ,取得了满意的效果 .
The trend relational grade in grey theories was made as the adaptive value of genetic algorithms in identifying system parameters. Both of the approachability and comparability were guaranteed in this method. Computer simulation showed that it overcomes the disadvantage of population premature in general genetic algorithms and got satisfied results.
