| 摘 要： | 提出一种基于N-R迭代方法的有限域优化搜索法,用于求解涡扇发动机数学模型。该方法不仅具有N-R优化迭代求解特色,还具有将初猜解附近划定域进行泛搜能力,使迭代运算具有强收敛性和平稳性。该方法所定义的迭代因子可通过编程自动调整,进而可以确定最小迭代次数及此意义下的最优迭代因子。

| Abstract: | An algorithm is developed based on the N-R(Newton-Raphson) iteration method to solve the nonlinear mathematical model of turbofan engine.It enhances the ability to search for the nonlinear equation solutions within a limited domain,which is dcsignated around the initial guess of solution and covers the genuine solution.Three iteration factors defined in this algorithm can be automatically readjusted by programming.Accordingly,the least times of iteration and corresponding optimum iteration factors can be found out from the program. |
