基于LabVIEW的三相异步电机变频调速策略
Variable Frequency Speed Control System Strategy Based on LabVIEW for Three-Phase Asynchronous Motor
摘要
Abstract
Nowadays the cost of measurement and control field is increasing and the system is becoming more and more complex. In order to solve above-mentioned problem, this paper combined VVVF technology and virtual instrument technology. In view of the flexibility and openness characteristics of virtual instrument and strong processing capacity of computer, it used the concise and straight forward graphical programming language Lab VIEW to realize the SPWM signal generation, and gave output to the inverter circuit by data acquisition card to control the three-phase asynchronous motor in order to replace the traditional control system. The system is stable and reliable. The cost of development is reduced greatly. The cycle of development is shortened and the flexibility of system is improved.关键词
