无论是设计组装一套系统,还是维修一套系统,在投入使用前都必须进行调试,调试的好坏将关系到系统能否在最佳状态下投入使用,因此,系统调试具有相当重要的作用。示波器是自动控制系统调试中经常使用的工具,如果使用不当,不仅不能正确调试,而且会造成设备的损坏。本文以直流双闭环调速系统的调试为例,分析用示波器进行系 Whether it is designing and assembling a system or repairing a system, it must be debugged before it can be put into use. The quality of debugging will be related to whether the system can be put into operation in the best condition. Therefore, system debugging plays a very important role . Oscilloscope is often used in automatic control system debugging tools, if used improperly, not only can not be properly debugged, but also cause equipment damage. In this paper, DC double closed-loop speed control system debugging, for example, analysis of the Department of oscilloscope
