航空发动机非线性数学模型的遗传算法

针对发动机非线性数学模型数值解法的收敛性问题应用了浮点数编码遗传算法，提出了将遗传算法与Broyden法相结合的方法。数值仿真结果表明，单独使用遗传算法时运算效率不高，而将遗传算法与Broyden法结合使用可有效的克服各自的不足，使得模型在保持原有运算效率的情形下扩大了收敛范围。

Application of Genetic Algorithm to Aero-engine Nonlinear Mathematical Model

Float point genetic algorithm is used to solve the convergence problem of aero-engine nonlinear mathematical model numerical solution. Simulation shows that the operation efficiency is not high by using the genetic algorithm alone. But by mixing genetic algorithm with Broyden method, the deficiency of each method can be avoided effectively and the convergence is extended with the substantial stability of original efficiency of the model being maintained.
