| 摘 要： | 结合传统的数值计算如拟牛顿法的局部快速收敛特性,以及遗传算法的全局收敛与群体搜索的优点,发展出一种新的混合遗传算法,使之具备全局快速收敛特性。通过两个算例及某型直升机在前进比为0.2状态下的配平,验证了该算法的可行性及高效性,从而为直升机的配平计算提供了一种新的成功的算法,同时也在传统数值分析方法和现代智能进化算法之间的有效结合做了一次比较成功的尝试。

| Abstract: | Combining the traditional numerical algorithms'(such as quasi-Newton method) quick convergence ability,and the genetic algorithm's advantages such as global convergency and mass searching,the paper develops a new hybrid genetic algorithm which can converge quickly in large scale.The following examples verified the algorithm's feasibility and high efficiency,so it develops a new approach for trimming the helicopter and makes a successful attempt to combine the traditional mathematical method with the modern ... |
