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

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.
