| 摘 要： | 提出了一种由阶跃响应曲线辨识系统传递函数的新方法—— 差分方程参数拟合法。方法由线性定常系统的辨识研究而提出，而后应用于开关变换器的小信号动态建模。文中用此方法对BOOST变换器进行建模，并将所建模型与采用状态空间平均法建模进行对比，验证了此方法所建模型的精确性

New Method for System Identification and its Application in Modeling for Switching Power Converter |
| |
| Abstract: | A new modeling method ?called parameters of difference equations fitting algorithm, which identified system with step-response curve ,was proposed in the paper. Researched on identifying linear time-invariant systems , and then applied it to modeling for the switching power converter The model of Boost converter was built using the method and was contrasted with the model built by state-space averaging method ,which proved that models using the new method is precise |
