摘要

现代电力驱动系统是电力电子装置与电动机及其驱动部分相结合的产物。在动力传动系统中，存在着各种非线性环节。本文首先对其非线性特性进行了分析。然后研究了耦合关系。研究结果表明，现代动力传动系统是一个包含多种非线性环节的耦合高非线性系统。介绍了功率变换器驱动和环变换器驱动在实际应用中存在的一些振荡或振动现象。分析了振动或振荡的机理。本文还提出了一种控制或抑制这种振荡或振动的新技术。讨论了该技术在实际减振工程中的应用效果，并给出了应用结果。

Study of coupled-nonlinearity and its control technique in modern power drive systems

Modern power drive systems are the product of combined power electronic installation with electric motor and its driven part. In a power drive system, there exist various nonlinear links. In this paper, the nonlinear characteristics are first analyzed. Then the coupled relation is studied. It is shown from the research results that the modern power drive system is a coupled high nonlinear system containing various nonlinear links. Some phenomena of oscillation or vibration exist in practical applications of power converter drives and cycloconverter drives, and are introduced. The mechanism of oscillation or vibration is analyzed. A novel technique of controlling or suppressing this oscillation or vibration is also suggested in this paper. The applied effect of this technique in practical vibration suppression engineering are discussed and the applied results are given.
