摘　　要：利用空-地武器的弹道表,用遗传算法(Genetic A lgorithm,GA)辨识武器的阻力特性,即阻力系数与武器飞行马赫数之间的参数化函数关系。针对3种不同的适应值度量方案,进行仿真研究。结果表明,3种适应值度量都导致算法的收敛,其中,幂比例适应函数效果最佳。Based on tabular ballistics of alr-to-ground weapons, drag characteristics, i. e. drag coefficients as a function of weapon flight Mach number, are identified using a generic algorithm. A simulation study is performed for three adaptation measurement concepts. The simulation results show that all the measurements lead to convergence of the algorithm, of which, the power proportional adaptive control has an advantage over the other two in terms of fitness of the original drag function.
