摘要

本文提出了一种改善V/f控制感应电机动态特性的方法。基本控制结构为带压降补偿和滑差补偿的开环V/f控制。此外，采用了一种新的电流阻尼器控制来抑制动态振荡。电流控制的改进是基于全模态综合。为了分析其动态特性，建立了复杂控制系统的数学模型，并应用了特征值轨迹理论。通过实验验证了分析结果。

Improvement of dynamic characteristic for V/f controlled induction motor drive system

This paper presents a method for improvement of the dynamic characteristic for V/f controlled induction machines. The basic control structure is the open-loop V/f control with voltage-drop compensation and slip compensation. Additionally, a new current damper control is utilized for suppressing the dynamic oscillation. The improvement of the current control is based on complete modal synthesis. In order to analyze the dynamic characteristic, the complex control system is built in a mathematical model and the eigenvalue loci theory is applied. The result of the analysis is proved by experiments.
