中文摘要:

      针对舵机频域特性测试的要求，基于虚拟仪器技术，采用chirp信号扫频法，设计了一套集数据采集、分析处理与显示回放于一体的虚拟频域特性测试系统。采用插入式采集卡（PC-DAQ）结构硬件平台，以LabVIEW为软件平台，所设计的系统具有测试简便、快速、准确的优点。

英文摘要:

      A frequency character testing system for rudder is designed based on virtual instrument technology，which uses the chirp signal as the source signal and has the functions of data acquisition，analysis and process，display and replay.The virtual system which utilizes the frame of PC-DAQ and LabVIEW has advantages of easy to test and quick and precise testing.
