一种测量交流伺服驱动系统的开环频率响应方法

A method to measure the open-loop frequency response in AC servo system

提出一种观测交流伺服系统的开环频率响应方法,通过注入伪随机信号进行闭环测量。通过功率谱的计算来辨识系统开环频率响应。

This paper presents an observation of the open-loop servo system frequency response method. Pseudo- random signal is injected into in order to proceed the closed-loop measurement. The open-loop frequen- cy response is identified by calculating the power spectrum.
