面向稳定平台伺服回路频率特性简易测试系统

The simple test system for frequency performance oriented to the servo loop of the stabilized platform

面向稳定平台伺服回路,给出了一种开环频率特性简易测试系统,该系统利用实验室最为常见的信号发生器和数字示波器加上稳定平台伺服回路本身构建,无需额外的硬件开销,数据处理在LabVIEW环境下完成,文中给出了实际使用中的干扰信号处理方法,实际使用表明,该简易测试系统具有搭建方便、开发难度低、实现成本低,测试精度高等特点,非常方便实验室现场应用。

Oriented to the servo loop of the stabilized platform,the simple test system for the frequency performance is given in the paper. The system is constructed from the laboratory of the most common signal generator and digital oscillo- scope with the servo loop of the stabilized platform, without additional hardware, data processing in LabVIEW environ- ment. This paper gives the actual interference in the use of signal processing method. It is shown in practical use that the simple test system with the advantages of putting up conveniently, low cost and high testing precision. The system is very convenient in the laboratory field application.
