不变性解耦理论在变频调速系统中的应用

The Application of Multivariable Invariance-Decoupling Theory to Speed Control of Variable Frequency

本文论述了CSIM变频调速系统,应用不变性解耦理论将紧密耦合的系统解耦为两个单变量系统,使之能够按照单变量系统进行设计。该设计方法简便,整个系统由单片微机实现了全数字控制。

The paper describes a CSIM driven by variable frequency. By using the invariance-decoupling theory, the seriously coupling system can be changed into two SISO systems. So it can be designed by single variable theory. This method is convenient. The whole digital control of the system is realized on a single chip-microcomputer.
