基于矢量控制的变频调速系统可靠性分析

摘要

Asynchronous motors based on vector control technique adjustment system were widely applied in industrial fields. A study of asynchronous motor model and the basic principle of vector control was made. Based on the theory of vector control and combined with asynchronous motor speeding regulating system, use roth criterion to analyze and calculate the parameter setting of the system transfer function for the stability analysis. And then the simulation verification was done using MATLAB. The effect rule of the parameter setting on the system was obtained.%基于矢量控制技术的良好特性,使得异步电机在工业领域得到广泛应用.首先从异步电机的数学模型出发,阐述矢量控制的基本原理.基于矢量控制原理,结合异步电机调速系统,采用劳斯判据分析并计算了系统传递函数参数对可靠性的影响.由仿真结果得出了参数变化对系统可靠性的影响规律.
