变频器的转差频率补偿控制

Slip Frequency Compensating Control Based on General Invertor

在通用变频器的基础上,通过将异步电机定子电流信号转换成转差频率信号,可实现转差频率的补偿控制,它具有简单实用的优点。本文分析了此方案的特点,介绍了采用模拟电路及微机实现的方法,并给出实验结果。

By changing stator current signal of induction motor into slip frequency signal,the slip frequency compensating control is realizated on a general invertor.It's simple and efficient.In this paper,the characters of this scheme are analysed.Both analogical and digital methods are introduced.Finaly,the test results are given out.
