基于虚拟仪器技术的电机转速测控系统设计

Design of Motor Speed Measurement and Control System Based on Virtual Instrument Technology

电机转速的测量与控制是现代工业生产和试验过程中经常遇到的问题。利用光电的方法将转速测量变为频率测量,以及利用PID算法进行转速控制是目前较为准确可靠的一种方法。采用美国国家仪器公司(NI)开发的LabVIEW图形化设计软件和ELVIS试验平台及其数据采集系统,设计了电机转速测量与控制系统。经过多次检验测试,该系统能够实现设计目的。

Motor speed measurement and control were issues frequently encountered in modern industrial production and testing process. At present,a more accurate and reliable way can be adopted is that using photoelectric method to turn speed measurement into frequency measurement and to command speed through PID algorithm. LabVIEW graphic design software and ELVIS test platform and data acquisition system which developed by American National Instrument designed motor speed measurement and control system were introduced,after repeated testing,results showed that the system can arrive at our design purpose.
