| 摘 要： | 在简要分析传统等效拟配初值选取方法不足的基础上,提出了一种基于Matlab信号处理工具箱提供的invfreqs函数的初值计算方法。整个计算过程不需要人工参与,所得拟配初值接近优化的终值,与传统初值选取方法相比,提高了拟配效率和成功率。仿真结果表明,该初值计算方法具有良好的工程应用价值。

| Abstract: | The disadvantages of traditional methods of calculating initial parameters of equivalent systems were shortly summed up,and a new calculating method based on the signal processing function of Matlab-invfreqs was presented.The engineers'participation is not essential to calculating process,and the derived initial parameters are close to the terminal optimized ones in values,which help to increase matching efficiency and matching probability of success.Simulation results show that the method is of good engineering application worth. |
