摘要:随着电力电子技术的发展，交流变频调速已经在逐步取代传统的直流调速传动，成为电气传动的主流。它以其优异的调速和起制动性能，高效率、高功率因数和节能效果，广泛的适用范围及其它许多优点而被国内外公认为最有发展前途的调速方式，其重要性日益得到重视，矢量控制更是提高了其性能。而模糊控制不需要建立精确的数学模型，而是运用模糊理论将人的经验知识、思文推理以及控制过程的方法与策略是由所谓模糊控制器来实现。因此模糊控制对那些难以获得数学模型或者是模型非常粗糙的工业系统，如大滞后，非线性的复杂工业对象实施者有独特优势。本设计通过建立起异步电动机的变频调速模型，利用MATLAB/Simulink软件进行矢量控制系统的仿真研究。验证将模糊控制应用于变频调速系统中验证是否具有比较好的控制特性。7042

Analysis of the application of intelligent control in AC vector control system
Abstract：With the development of power electronic technology, AC variable frequency speed regulation has been gradually replaced the traditional DC motor drive, become the mainstream of electric drive. With its superior speed and braking performance, high efficiency, high power factor and energy-saving effect, wide application range and other advantages, is recognized as the most promising way to speed at home and abroad, its importance has been paid more attention to, vector control is to improve its performance. Fuzzy control does not need to establish accurate mathematical model, but using the fuzzy theory, the method and strategy of knowledge, reasoning and control process are realized by the fuzzy controller. So the fuzzy control for those difficult to obtain the mathematical model or industrial system model is very rough, such as the big lag, nonlinear complex industrial object implementation has unique advantage. This design by establishing variable frequency speed control model of induction motor vector control system, simulation was conducted using Matlab/Simulink software. fuzzy control is applied to the verification of variable frequency speed regulation system to verify whether has better control characteristics.
