矢量变频器在工业控制中的应用研究

The Application of Vector Inverter in Industrial Control

随着工业控制的多元化和复杂性,变频器在工业控制中的应用越来越广泛。由于变频器具有性能良好、调速区间宽、运行平稳和智能化等优点,使得变频调速变得简单、可靠,对于控制精度较低的系统,普通变频器完全可以满足要求,对于控制精度较高,动态品质需要完善的系统,采用矢量变频器是一种很好的控制方案。在交流调速系统中,矢量控制技术是比较高效和完善的,替代传统的直流传动技术,表现出很好的鲁棒性和动态品质。

with the diversification and complexity of industrial control, the frequency converter is widely used in industrial control. Because the frequency converter has good performance, wide speed range, the advantages of stable operation and intelligent, makes frequency control of motor speed is simple, reliable, the low control precision of system and general inverter can completely meet the requirements, for high precision control, dynamic quality need to improve the system, adopts vector frequency converter is a kind of very good control scheme. In ac speed regulation system, vector control technology is relatively efficient and perfect, which replaces the traditional dc drive technology and shows excellent robustness and dynamic quality.
